A new study has found that the type of mosquito that transmits viruses such as Zika and dengue fever can be reduced by eating sugar from flowers before blood.
The study, led by the University of Glasgow Center for Virology Research, showed that the Asian tiger mosquito or yellow fever mosquito, boosted immunity in its guts after it fed on sugar, and this protects the females of the species from infection.
Adult mosquitoes feed on plant nectar to build their energy, but they need blood to reproduce.
As a result, they transmit viruses, including the chikungunya virus, which is a common problem for the entire world.
It is not clear why sugar protects mosquitoes from infection, but the researchers believe it may be partly responsible for the “high sensitivity and transmission of arthropod viruses by this species of mosquito”.
Dr Emily Bondville, a molecular entomologist at MRC University, one of the study’s co-authors, said the findings highlight the importance of feeding mosquitoes sugar to lower infection rates worldwide. Overall, the results reveal the critical role of sugar feeding in mosquitoes’ antiviral immunity, which in turn reduces the potential for arboviruses to spread, which are a major threat to people.
In the future, this could aid the development and implementation of vector control strategies such as sugar bait, aimed at reducing arbovirus transmission.
The study was recently published in the scientific journal PLOS Pathogens.
What is the disease of the knees?
Dengue fever is a viral infection transmitted by the bite of a mosquito. It is most common in tropical and subtropical regions, and is particularly fast in poor urban, suburban and rural areas. Other names for the disease: Dengue – Dengue fever – disease of the knees – Bone-breaking fever.
Mosquitoes or mosquitoes usually disappear with low temperatures in the winter, but they do not disappear completely, as they have their ways of hiding during very cold times, and some types of mosquitoes enter what is called a “hibernation state”, especially in areas where a warm spring comes after a cold winter, It stays in its lairs until the temperatures improve, and then starts reappearing.
We are going to devote this post to answering the question “When does winter mosquito appear?”, mentioning how to get rid of it at home, so continue reading.
When does the winter mosquito appear? Some types of mosquitoes go into hibernation during cold weather, while others wait for the spring to come out, and other types come out on warm winter days, for this reason mosquitoes appear on sunny days in winter.
A few mosquitoes hatch in the fall, hiding at the bottom of swimming pools to protect themselves from freezing, while adult mosquitoes die when the weather gets cold, but leave their young, or “winter eggs,” which live in frigid temperatures, and lie dormant in the ground like Seeds, until temperatures improve and come out then.
Every woman is keen to make her home clean and free of any insects, and she does everything in her power to achieve this.
Through the following lines, we will present to you simple and effective ways to get rid of mosquitoes:
Check doors and windows: the main source of insects entering your home are the gaps in the windows and doors, be sure to seal them, to prevent mosquitoes from entering completely, and there can be holes in the metal wires installed on the windows, look for them and treat them as well.
Use an ultrasonic insecticide: Ultrasound insecticide devices emit annoying frequencies to insects, and drive them out of the house, and the beautiful thing is that it is not harmful to you or your family, as it does not release any chemicals that negatively affect health.
Expel it with camphor oil: camphor oil has many health benefits, such as treating burns, relieving pain, and treating arthritis pain , as well as a good mosquito repellent, all you have to do, put a quantity of it in every room of the house, with all doors and windows closed,
Leave it for 15 to 20 minutes, then open it again, you can do this before leaving the house so that the smell does not bother you.
Kill its larvae with garlic: Garlic contains natural antioxidants, helps prevent Alzheimer’s disease , and lowers blood pressure, in addition to being mosquito repellent thanks to its strong pungent smell and properties that help exterminate mosquito larvae, all you have to do is crush some garlic cloves, and boil them in Water for a while, pour the mixture into a bottle, and spray all corners of the house with it, this will prevent mosquitoes from approaching your house.
Get rid of it in an ice bowl: We exhale carbon dioxide so mosquitoes are attracted to us, and it also emits snow, so all you have to do is put it in a bowl, and when mosquitoes are attracted to it, close the lid. Although this method is time consuming, it is very effective and safe for your family.
Use the mosquito trap: The mosquito trap looks like a traditional solution, but it is effective and inexpensive, and it is available in markets and supermarkets, use it to kill mosquitoes quickly.
Mosquitoes are relatively small insects, averaging over 6 mm in length, weighing about 2.5 milligrams, and their body consists of three basic parts: the head, thorax, and abdomen.
What is a mosquito?
Mosquitoes , a group of about 3,500 species of small insects that are a type of flies, mosquitoes have a slender segmented body, one pair of wings, three pairs of legs, antennae, and a proboscis. The life cycle of a mosquito consists of the egg, larva, pupae, and adult. On the surface of the water, they hatch into mobile larvae that feed on aquatic algae and organic matter.
Females in most species have a tube-like mouth (called a proboscis), which can pierce the skin, in what is called a bite, in order to extract blood, and proteins that are necessary for reproduction, Thousands of species feed on the blood of different hosts: primarily vertebrates, including mammals, birds, reptiles, amphibians and even some species of fish, and some invertebrates, especially other arthropods. This blood loss is rarely significant to the host, and mosquito saliva can cause Transmitted to the host with the bite causes itching and rash.
In addition, many types of mosquitoes inject pathogenic organisms with this bite, and thus are carriers of a large number of diseases, such as malaria, yellow fever, West Nile virus, dengue fever, filariasis, Zika virus, and others, so mosquitoes kill more than any other animal More than 700,000 years old, the oldest known mosquitoes with an anatomy similar to modern species, are found in the 79 million-year-old Canadian amber of the Cretaceous period , and the larger sister species with more primitive features are found in Burmese amber, which range from 90 to 100 million years ago, two mosquito fossils were found that show only very little change in modern mosquitoes from 46 million years ago, and recent studies indicate that the earliest divergence of mosquitoes, between the lineages leading to Anophelinae and Culicinae occurred 226 million years ago.
Basic parts of a mosquito’s body
Mosquito structure. The extent to which people know very little about mosquitoes. Most people are familiar with the annoying, blood-sucking, buzzing bugs. Not many people know that only female mosquitoes can bite, and that some types of mosquitoes can travel up to 40 miles to eat their food. Although mosquitoes are often viewed as a pest, knowing about a mosquito’s body composition and life cycle can give interesting and useful facts.
Mosquito body components: Like many insects, the body of a mosquito can be divided into 3 sections: the head, the thorax, and the abdomen.
A mosquito’s head is packed with sensory equipment, which helps mosquitoes find people and animals to feed on. The head of the mosquito is round and bears the two compound eyes of the insect.
Be aware that compound eyes are made up of hundreds (maybe thousands) of tiny lenses. This is what helps the mosquito to carry out precise attacks.
A mosquito’s head also bears antennae and mouthparts.
The male mosquito has mouth parts that allow him to suck nectar, while the female allows the mouth parts to cut through the skin and prepare her meal from human blood, depending on the blood type that the mosquito loves .
Although both sexes feed on nectar, only females bite.
Mosquitoes’ antennas help them sense movement in the air.
They are so sensitive that using them a male mosquito can distinguish between a female mosquito’s wing stroke and a male mosquito’s wing stroke, which is one of the reasons why mosquitoes buzz around the ear and because female mosquitoes also like to get carbon dioxide.
The compound eyes
The mosquito has two large compound eyes covered with small lenses called ommatidia, which are able to detect any slight movement, and on the head of the mosquito there are also eyes, which are simple photosensitive eyes, that can detect differences in light.
Mosquitoes have their own antennae, and these horns stick out of their heads, and they contain sensitive receptors that detect carbon dioxide in human breath, from distances of more than 100 feet, and can detect the smell of chemicals that are released in human sweat.
There is also in the middle between the antennae, a hose with a long serrated tip, used to puncture the skin and suck blood, and this hose contains two tubes, one of which injects saliva, which contains a pain reliever and a mild anticoagulant, and the second that draws blood. these are the chemicals causing allergic reactions too mosquito bites.
The thorax of the mosquito is attached to the head, and it consists of an onyx, a pair of wings, a pair of halters, and small wing-like devices used for orientation, that grow from the thorax, and the legs come from the chest, and they are six, with small claws at the end of each to help mosquitoes survive.
The second part of a mosquito’s body is the thorax. The thorax in the mosquito’s body is divided into three small sections, the Prothorax, which is closest to the head, the Mesothorax, which is the middle part of the thorax, and third one which is the part closest to the back end.
Each of these subsections contains a pair of legs. The mesothorax has wings while the prothorax has a pair of spiracles, which are small holes that allow air to enter the mosquito’s body. Instead of lungs, mosquitoes have a series of tubes that connect to their body. These tubes are called the trachea and they help deliver oxygen to the mosquito’s various tissues.
Belly or Abdomen
The abdomen hangs from the rib cage and serves as the stomach and lungs of mosquitoes.
The rear end of the mosquito is called the abdomen. There are 10 sections in the mosquito’s abdomen, each with a pair of respiratory openings except for the first, ninth, and tenth sections. The ninth section contains a hole for the passage of sexual materials. The tenth section contains the male or female sexual organs, according to the sex of the insect.
The respiratory openings
Small openings called (spiracles) open the sides of the abdomen, allowing mosquitoes to capture air, where the abdomen carries the blood received by the mosquito, and the abdominal nerve sends signals when it is full, and the eggs of the female are stored in the abdomen, and scientists use these small differences in the shape and color of the abdomen , as well as in the length of the upper jaw and wings, to identify the different species of mosquitoes.
Mosquito life cycle
The first stage of the mosquito’s life cycle is the egg. The eggs are usually laid in water or moist soil. Depending on the species, the eggs can stick together or float independently, on their own. Most mosquito eggs hatch after 48 hours. If the eggs are laid close to winter, the eggs can survive, until they hatch when temperatures rise.
Allergic reactions and skeeter syndrome are the basic harms of mosquito bites, but there are many other dangers that can be happen if a mosquito pierce your skin, including the below viruses…
Symptoms of this virus are mild, for most people. They are fever, rash, joint pain, and red eyes. The real danger is to the pregnant woman and the fetus.
This virus is linked to a birth defect called microcephaly, which causes microcephaly and brain damage. Mosquitoes spread this disease in many parts of the world including Brazil, other countries in South and Central America, the Caribbean, and Southeast Asia.
It is rare in the United States, but it appears in places popular with tourists such as Puerto Rico, the Pacific Islands, Latin America, and Southeast Asia.
The person suffering from dengue fever suffers from problems such as rash, fever, headache, easy bruising, and bleeding gums. It can sometimes lead to hemorrhagic fever, which can be fatal. Therefore, the mosquitoes that cause this fever are among the most dangerous types of mosquitoes .
The only FDA-approved vaccine is for children ages 9 to 16 who have been previously infected with one of the four dengue viruses to help them avoid being reinfected by one of these viruses.
West Nile Virus
A person who has been bitten by a mosquito carrying this virus may not have any symptoms. However, some people may have a fever, joint pain, diarrhea, vomiting, or a rash. Pay attention to rare complications, such as brain infections called encephalitis or meningitis.
There is no vaccine for this disease, which appears in every state, except for Alaska and Hawaii.
It is rare in the United States, but nearly half of the world’s population is at risk of contracting this disease. Most cases occur in sub-Saharan Africa, but transmission also occurs in South America, southern Asia and many other regions. Symptoms include fever, headache, chills, and vomiting.
This disease takes its name from one of its symptoms, jaundice, which can make the skin and eyes look yellow. Less serious infections cause headaches, backaches, chills, and vomiting. There is a vaccine that prevents this fever, so a person must get the vaccine if he wants to travel to places in Africa and Latin America where this disease is common.
A mosquito-borne disease , it takes its name from an African language and refers to the curved appearance that people may have due to severe joint pain. Symptoms also include a rash, headache, nausea, and fatigue. The disease spreads mainly in Asia and India, and has begun to spread to Europe and the Americas. There is no cure for this virus, however most people recover. In some cases, symptoms can last for months or even years.
The eggs hatch and become watery larvae or larvae, which swim in a jerky, twisting motion. In most species, the larvae feed on algae and organic debris, although a few are predatory and may feed on mosquitoes. The life cycle of mosquitoes varies greatly, depending on the species.
Mosquito-borne diseasescontrol methods
The best effective way to avoid getting infected with viruses spread by mosquitoes at home or while traveling somewhere, or to get rid of mosquitoes by natural methods is to prevent mosquito bites. Mosquito bites can be more than just annoying and itchy bites. They can spread viruses that cause illness and, in rare cases, death. Although most mosquito species are just annoying and not dangerous, some mosquito species in the United States and other regions around the world spread viruses that can cause disease. Mosquitoes bite during the day and night, and they live indoors and outdoors, in warm, humid places. Mosquito season begins in summer and lasts until autumn. To avoid mosquito bites, various methods can be followed, including:
What do mosquitoes hate?
Use insect repellent: When used as directed by the Environmental Protection Agency, insect repellent is safe and effective, even for pregnant and breastfeeding women.
Wear long-sleeved clothes and long pants.
Try to keep mosquitoes outside, by using air conditioners. In the event that it is not possible to protect the person from mosquitoes at home, it is recommended to sleep under a bed net, which is an effective mosquito control method .
If you experience symptoms such as fever, headache, joint and muscle pain, and rash during travel, see your health care provider immediately for appropriate treatment.
The worst thing that can happen to you from mosquitoes is that a mosquito bite occurs to the eyelid, as swelling and puffiness occur in the eyelid because it is a sensitive area.
Unfortunately, the mosquito bite causes the eyelid to itch in this area, which makes the patient want to scratch it by any means, which worsen it.
The main cause of swelling caused by mosquito bites on the eyelid, more than any other area of the body, is the sensitivity of the skin in this place.
Even a simple mosquito bite in the eyelid can cause so much swelling that the victim cannot close his eye.
Another reason for this swelling is the accumulation of fluid on the eye due to the bite, and if you lie on your back, you will find the eye has become more swollen, and the color of the eyelid will turn into a pale pink.
What does a mosquito bite on eyelid look like? in the case of mosquito bites on the eyelid, the swelling is somewhat soft and similar to a water balloon, but as soon as this swelling goes away, you will see the red area in which the mosquito bit you.
If you have bad luck and a mosquito bites your kid’s eyelid, don’t panic, you can quickly put some ice on the affected area, as this will reduce the swelling and promote the cure for the bitten eyelid.
10 Best Treatment Methods for mosquito bites on eyelids for kids
Aloe Vera Gel: useful in treating mosquito bites by applying aloe vera gel to the eyelid which have a soothing effect on the affected area, relieving itching and swelling of mosquito bites. The antibacterial properties of the gel will also prevent the spread of infection, which is why we recommend applying the gel as soon as possible from the time of the mosquito bite .
Antihistamines: If you are afraid of an allergic reaction due to mosquito bites, it is recommended to take an antihistamine, but before you do anything, please consult your doctor as it may has side effects such as drowsiness.
Vinegar: Take a teaspoon of vinegar and mix it with a tablespoon of water, then take a clean, soft cloth and dip its edge into this mixture. Vinegar helps treat mosquito bites for kid’s eyelids. Next, place the edge of the cloth over the bitten area of the eyelid. This will reduce swelling and relieve itching after mosquito bites. If using this remedy on children, have the child lie on his back and make sure his eyes are completely closed. Treatment of mosquito bites using vinegar solution may take some extra time, but it is effective in reducing swelling.
Toothpaste: Yes, Toothpaste is also useful, as it can be applied over the swelling and then put some ice on the affected area until the itch is gone.
Honey: Of course, Honey has natural anti-inflammatory properties and thus is an effective home remedy for mosquito bites for the children’s eyelid. You can simply put honey on the affected eyelid, and leave it for some time. It helps relieve pain and control swelling and inflammation, and yes, you can see results quickly. In the case of children, you should wash after applying honey as it tends to attract other insects that do more harm than good.
Dry soap: Dry bath soap is also a good home remedy for mosquito bites on the eyelid area. Antiseptic soap works well in controlling the swelling caused by bug bites, and so does mosquito netting. Make sure the soap is dry before using it – a new one is preferred – because wet soap can get into the eyes and cause irritation. The herbal soap found at the perfumer and intended for these purposes can also be used.
Epsom salt: Yes, it is also one of the home remedies commonly used to get rid of a mosquito bite on the kid’s eyelid. You can dilute the Epsom salt in water and take a cotton ball, dip it in the solution, and then apply it to the eyelid of the bitten eye. This will help reduce the inflammation, swelling and pain caused by mosquito bites on the eyelid of your child.
Herbal oil: There are plenty of herbal oils available in the market that can be used effectively as a home remedy for mosquito bites. Herbal oils control inflammation and prevent any swelling from growing. The oil most commonly used in case of mosquito bites to the eyelid is lavender oil. Coconut oil is also used because of its anti-inflammatory properties and is also a good home remedy.
Garlic and Onion: This is also an effective home remedy against mosquitoes and is easily available at home. Chopped garlic and onions can be applied directly to the eyelid of the affected eye to reduce the swelling, pain, and inflammation caused by mosquito bites. If you experience pain, don’t use garlic or onion slices directly on bites that inflamed and become a wound.
Baking soda: Yes, Baking soda is a very useful home remedy thanks to its many properties, and it is not surprising that it is useful for mosquito bites in the eyelid area of toddlers. Baking soda has been used as a remedy for various ailments since ancient times, and when mixed with warm water it becomes a useful alkaline solution. The baking soda solution helps calm inflammation and prevent any swelling from growing, and the effect can be seen within a few minutes.
Precautions when treating eyelid bites of children
Do not panic if the eyes swell to a large extent after sleep, this is normal because of the accumulation of fluid as we mentioned earlier.
Whatever treatment you use, be careful not to drop even one drop into the eye, especially if you are treating children.
The best way is to use an ice pack as it will treat the swelling immediately. If any complications occur, you should consult a doctor immediately.
Don’t hesitate to ask for help for your bites or unknown insects
It is known that when exposed to a mosquito bite, it feeds on the blood of the person who has been bitten. It is logical that a very important question arises in the minds of citizens, which is can a mosquito transmit hepatitis C or other hepatitis viruses when it bites an infected person and then bites another person?
And preventive medicine experts at the Ministry of Health confirm that: fortunately, the mosquito does not transmit the C virus through its bites, as well as insects, for the following reasons.
It is known that Virus B and Virus C infections are transmitted through exposure to blood only.
When exposed to mosquito insect bites, the unique biological structure of its needle consists of two separate channels, where the first channel works to inject the skin with mosquito saliva, which contains many substances that facilitate the penetration of the skin, while the second channel of the mosquito needle is through which blood is sucked from the victim
The channel that sucks the victim’s blood has valves that only allow the blood to pass in one direction from the victim to the mosquito’s stomach and does not allow the opposite, that is, blood from the mosquito to enter the victim.
Hepatitis C and B viruses are very sensitive viruses that depend on selecting suitable hosts to live in their livers, and since mosquitoes do not have a liver, these viruses cannot survive for long periods inside the body of the mosquito.
Entomologists found that mosquitoes rarely bite two people in a row at the same time. After they bite a person and suck their meal of blood, they fly away until they digest that meal and then return to feeding.
Mosquitoes transmit malaria and yellow fever, and they are transmitted through their saliva and not through blood.
Other Diseases transmitted by Mosquitoes:
We must be concerned about the diseases transmitted by mosquitoes annually, every year more than a million people die and thousands are injured due to the bite of this annoying insect, according to a website report. deter outdoors.”
Review the most important diseases carried by mosquitoes and transmitted to humans through their bite:
It is a disease caused by the Plasmodium parasite, which mosquitoes transmit to red blood cells by stinging the patient. The parasite destroys red blood cells and multiplies in the human body.
Fever and chills are one of the symptoms of the disease, in addition to vomiting, headache, sweating and coughing.
Transmitted by Aedes aegypti mosquitoes, symptoms range from muscle and joint pain to headache and fever, and may be fatal in advanced stages. Although the vaccine exists, it is subject to some limitations, as it may provoke fatal reactions from the body.
Several days after the mosquito bite, the victim suffers from fever, headache, vomiting, dizziness, constipation, severe and persistent muscle pain, and if not treated, it may lead to meningitis or the destruction of vital organs.
This virus spreads in Africa, Asia and the Indian subcontinent, but the mosquitoes that transmit the disease have moved in recent decades to Europe and the Americas.
It causes a sudden onset of fever with severe joint pain that often disables a person greatly, in addition to muscle pain, rash and headache.
Zika virus infection is transmitted primarily by the bite of infected mosquitoes of the genus Aedes, especially Aedes aegypti in tropical and subtropical regions.
The incubation period for Zika virus disease (the time from exposure to symptoms) is estimated to range from 3 to 14 days. Most people infected with Zika virus have no symptoms, and symptoms are usually mild and include fever, rash, conjunctivitis, muscle and joint pain, malaise, and headache, and usually last for two to seven days.
The Aedes mosquito usually bites humans in broad daylight and peaks in the early morning and late afternoon/early evening hours. It is the same mosquito that transmits dengue, chikungunya and yellow fever.
So if you feel any of these symptoms, you should go to the doctor immediately.
Are Mosquito Bites Worse Now Than They Were in the Past?
It has recently been noticed that mosquito bites have become more and more severe than before, and hardly a day in the clinic is free of cases of mosquito bites.
Mosquitoes are a type of insect, widespread in all parts of the earth except Antarctica and Iceland.
Like other insects, it has many types of up to 3000 species and differs from one place to another. However, in recent decades, given the increased intensity of air transport between countries, it is not surprising that there is a common type of mosquito in Southeast Asia, spread in America or in the Middle East.
One example of this is the presence of the Asian Tiger Mosquito , which has become very popular recently, as it has been seen and photographed by many people, and this mosquito is characterized by black and white colors on the body and legs, and perhaps its recent presence among us is what It causes the body to react severely to its bites; Since we were not used to this type before.
Usually, the person does not feel the mosquito bites when it occurs, as the mosquito secretes substances that numb the skin and work to prevent blood clotting factors to feed on it for as long as possible, but after that, itching, redness and swelling begin in the place and this is due to the body’s reaction to the mosquito’s saliva.
It is worth noting that it is the female mosquito that feeds on blood; To obtain the protein necessary for the formation of eggs, as for the male mosquito, he feeds on the flowers only. Thus, the female mosquito is the most deadly animal on earth, as it is a carrier of many viruses and diseases, the most important of which are malaria, dengue fever, yellow fever and West Nile fever.
How do we prevent mosquito bites?
The first step: controlling the water sources, which are the main place for mosquitoes to breed and lay their eggs, as mosquitoes need water to reproduce and lay their eggs, and the first two stages of a mosquito’s life (larvae) are in the water; It is essential to get rid of standing water around homes, under plant beds and to keep water tanks tightly closed.
The second step: I mentioned previously that mosquito bites may cause itching and swelling, and may cause the transmission of viruses and diseases. Therefore, the use of insect repellents on exposed skin is a necessary step to prevent bites, especially in children, who are more susceptible to allergies and bloating.
The place of the bite should also be washed with cold water and soap as soon as possible, and a dermatologist should be consulted if the sensitivity is severe, so that allergy treatments, cortisone and antibiotics can be dispensed if necessary.
How to make a effective cheap trap for flies and mosquitoes at home?
Tools needed: Large, empty bottle, protector or cutter, the provided marker or felt-tip pen, 1 cup of boiling water, ¼ cup brown sugar, 1 gram of yeast, adherence tape.
Preparing the bottle: we use a marker to draw a mark in the middle of the bottle. The center can be measured with a ruler or tape and the mark is on the entire circumference of the bottle, using a knife we cut the bottle in half according to the marks we drew, we do not throw away the top, but leave it, pay attention to the edges of the bottle after cutting because Sharp so you can wrap the edges with masking tape to avoid cutting your hands.
Preparing the trap to get rid of the mosquitoes: We put a certain amount of water in the pot until it boils completely and then the water can be used in the trap, in the half with the bottom of the bottle we pour brown sugar, taking care not to leave the sugar on the wall of the bottle from the outside, carefully add boiling water to the brown sugar Let the mixture stand for an hour to cool, later add the yeast to the sugar and water and you won’t need to stir because the yeast absorbs the sugar and emits carbon dioxide to attract mosquitoes. Installing the trap: We bring the other part of the bottle and place it in the opposite half inside the first half.
We put the adhesive tape on the edges to install the trap. Place the trap in a place close to flies and mosquitoes. Every two weeks we wash the trap and repeat the process until it remains effective in eliminating flies.
Mosquitoes are known to be the most important carriers of dengue, malaria and Zika viruses, all of which are life-threatening diseases. While these diseases are commonly known, there is one mosquito allergy you may not have heard of: Skeeter syndrome.
Serious symptoms and allergic reactions
Mosquito bites can cause severe allergic reactions, whose primary symptoms include:
Lymphangitis, the bacterial infection spreads to the lymph ducts. More dangerous because the infection can enter the bloodstream. (This is called sepsis.)
But if you notice any of the following symptoms, see a doctor immediately as they may indicate a serious risk:
The difference between skeeter syndrome and a skin infection
The signs of skin infection after an insect bite and skeeter syndrome are almost the same and they are itching, redness, swelling of the skin, and pain, which are common symptoms that may confuse you whether it is an infection or an allergy, but while mosquito infection occurs a few days after the bite, skeeter syndrome occurs immediately.
They are both different but they are related in one way or another because victims of skeeter syndrome are at risk of developing a skin infection when people scratch their skin from itching, it worsens the condition of the skin and this affects the healing process. This sensitivity may lead to skin injury as well.
What is mosquito allergy? What are the symptoms?
Mosquitoes are annoying insects, whose bites are usually found in the summer, that cause allergic reactions. Mosquito allergy can occur in the form of small or major local reactions, or even systemic reactions
There are more than thirty proteins in mosquito saliva, many of which cause allergic reactions. With a mosquito bite, the body’s immune system reacts allergicly to these proteins and swelling occurs where the mosquito bites
What kind of reactions occur in mosquito bites?
As a result of mosquito bites, swelling occurs 2-10 mm in size with red color in a short time. In the next 24-36 hours the number of itchy bumps of similar size increases and decreases within a few days. Local reactions, usually larger than 3 cm in some people, may occur soon after a mosquito bite. After a while, the reactions that occur may collect water. In some people, this may be in heat with a significant localized reaction. These children are healthy children without any other disease. Major topical reactions usually resolve within 3-10 days. Rarely, systemic allergic reactions such as acute common urticaria, serum sickness and anaphylactic shock (anaphylaxis) may occur in some children.
Which children have a high risk of systemic allergy?
Because young children are not immune, there is a higher risk of developing a systemic reaction. In addition, the risk is higher in children with congenital or acquired immune disorders and mastocytosis
How is the diagnosis made?
To diagnose mosquito allergy, a detailed history and examination is required. In patients with significant local or systemic allergies, mosquito allergy can be diagnosed by allergy tests from the blood or from the skin. However, allergy tests from blood and skin do not show a high sensitivity. Therefore, the negativity does not mean that there is no mosquito allergy. There is no need to perform allergy tests in people who naturally react to mosquito bites
Children who develop systemic reactions also need to be investigated for immune failures
What are you expecting?
Itching for 3 or 4 days.
Redness or redness lasting 3 or 4 days.
Swelling may last 7 days.
Bites of the upper face can cause severe swelling around the eye, which does not harm vision. The swelling is often worse in the morning after lying down all night. It will get better after standing for a few hours.
Call your doctor if
The bite looks infected (redness becomes larger after 48 hours)
The bite becomes painful
You think your child needs to be seen
Your child gets worse
What should be done in treatment?
The first thing to do in treatment is to keep away from mosquitoes. In cases where mosquito exposure is expected, protective clothing should be worn to prevent them from biting, and the body should be sprayed with mosquito repellents.
These medicines can be used in children over 2 months old. At night, it is useful to have bed nets for the baby to protect him while he sleeps. The application of protective drugs to the bed net increases the effect of the protection.
Additionally, antihistamines may be given as a preventive agent for a period of time in children known to react against mosquito bites.
As a result of a mosquito bite, in cases where there is a reaction, antihistamines should be given orally and cortisone creams should be applied to the area of swelling and redness for 5-10 days. In systemic reactions, oral corticosteroids should be given for 5-7 days. Antipyretic drugs should be given in large local reactions with heat. Antibiotics should not be used if there is no infection
There have been studies on the treatment of mosquito allergy vaccines, but its benefit has not been proven
Does mosquito allergy improve over time?
In young children who are allergic to mosquitoes and react increasingly violently, after the age of 5 years, the sensitivity disappears in the main reactions
As a result:
Mosquito bite allergy is very common in summer
Some of these children have significant local or systemic reactions
In some underlying disease states, the risk of systemic reactions is even higher
Diagnosis is made by history and examination and is supported by allergy tests that are carried out from the skin and from the blood
In treatment, mosquitoes should be avoided and preventive measures should be taken
In cases where reactions develop, medications containing antihistamines and corticosteroids should be used according to their severity
Mosquitoes use three types of visual, olfactory, and thermal information to guide humans. The mosquito works like a magnet, and it has minute receptors in its antennas and head that enable it to detect human odors up to 50 meters away, and it smells carbon dioxide and considers it an address for the presence of humans from a distance of 10 to 50 meters, and it senses the temperature of the target at a distance less than a meter. The higher the carbon dioxide emissions, the easier it is for humans to convert, which is why adults and obese adults are more susceptible to mosquitoes than children.
Pregnant women are more attractive to mosquitoes than others. Mosquitoes are attracted to people with type O blood twice as much as blood type A, while type B are attracted to them less than blood type O, and more than blood type A. It is often noticed that mosquitoes prefer some humans over others as they have like magnets
Mosquitoes are considered one of the most annoying insects to humans, as female mosquitoes feed on human blood during deep sleep through their bite, which makes them suffer throughout the day from severe pain, and according to experts, mosquitoes buzz around the ears because of their love for carbon dioxide gas coming out of the nose, and because His love for the smell of sweat in the ears, hair and neck, and it is no wonder that he is one of the insects that loves unpleasant odors, and lays their eggs on stagnant water, as males and females may mate at the human head, and the buzzing sound results from the friction of the two wings strongly, and mosquito damage is not limited to disturbance. In fact, mosquitoes transmit dangerous diseases to humans by transmitting germs to the blood of a healthy person when sucking his blood.
Why do mosquitoes buzz in our ears?
Nothing feels like summer more than an outdoor barbecue gathering, especially after the dreary winter months. But the enemy of summer gatherings remains: the whine of mosquitoes that circles our ears.
So why are these blood-sucking insects hovering around our ears in the first place? And why are they making such an annoying noise?
“Tinnitus is mostly just a side effect of mosquitoes banging on their wings,” said Michael Riel, professor of entomology at the University of Arizona. “The sound doesn’t have a long range, so you notice it more when it’s flying around your ears.”
This is likely the sound you hear from a female mosquito. That’s because male and female mosquitoes live completely different lives. Males usually roam and inhale the nectar of flowers, without much concern for humans. However, females need to find a blood meal after mating in order to have enough energy to produce eggs. In fact, female mosquitoes were equipped with unique tools to shelter their next victim.
“From afar, female mosquitoes are attracted to the carbon dioxide we exhale in cone-shaped columns from our bodies,” Riel told Live Science. The carbon dioxide stimulates the female mosquito to begin searching for a host, and to fly back and forth to follow this concentration gradient back to the source.”
In other words, mosquitoes are buzzing around our heads because that’s where we expel the most carbon dioxide.
As it approaches, the female mosquito compresses body heat and a column of carbon dioxide falls on the victim. The female mosquito uses the taste sensors on her feet to determine if a human, or any animal carrying blood, is suitable for her next meal. And while some studies suggest blood type O is best, Riel remains skeptical, finding no convincing research on blood type and mosquito needs.
Instead, other factors, such as genes and even a person’s diet, are believed to play a larger role.
Your skin “gives off this unique combination of scents that will be more attractive to some mosquitoes than others,” Riel said. Another study found that female mosquitoes were more attracted to men who had less diverse bacteria on their skin compared to men with more diverse skin bacteria.
When the female flies toward the target, she beats her wings about 500 times per second at a frequency of 450 to 500 hertz. This frequency is transmitted to note A, which, coincidentally, is what the orchestra itself tunes to before the concert.
But, while we may easily see mosquitoes buzzing around our ears, Riel noted that most mosquitoes are not attracted to our heads. Alternatively, these vampires may be more inclined to seek out our feet, which contain bacteria that emit an alluring odor to mosquitoes. However, he said, most people probably won’t notice a mosquito buzzing around their ankles.
A 1996 study published in Trends in Parasitology found that female Anopheles mosquitoes, which are responsible for transmitting the malaria parasite, are attracted to bacteria on human feet. It is these same bacteria, Brevibacterium linens, that give Limburger cheese its distinctive aroma. A 2013 follow-up study in the journal PLOS One confirmed that mosquitoes are actually attracted to Limburger cheese.
As for avoiding mosquitoes, your best bets are to wear long, light-colored clothing, use insect repellent and stay away from mosquito hotspots (wetlands, for example) at dusk and dawn, when mosquitoes are most active, Live Science previously reported.
The ringing of mosquitoes around the ear is due to many reasons. We will address some of these reasons, which are:
1- Female mosquitoes are known to always spin around anyone’s head because they want to get a large amount of carbon dioxide, in addition to that they are also noticeably attracted to the smell of both sweat and heat as well as to all the pungent smells all, they have powerful sensors that help them In search of a lot of different places that also enables her to be attracted to so that she can access food in an easy and simple way.
2- It is also noticeable that mosquitoes buzz in a noticeable way around the ears of people who are returning from exercising or from the gym in general, because these people have made a great effort and therefore the smell of sweat for them works to attract mosquitoes to them, and this is due to the fact that mosquitoes prefer octenol It is one of the chemicals that are found in the smell of sweat.
3- The buzzing of mosquitoes around the ear is also due to mating between them. It is noticeable that male mosquitoes usually form swarms between them for mating and that is above the body, and they often use the human head for this, and it is usual that this swarm consists of many males Mosquitoes, which number in the thousands, and there are also female mosquitoes around you that become the target of these males.
This is why mosquitoes buzz around one person’s ear and not the other
Experts emphasized that the cause of mosquito buzzing around the human ear is due to a number of reasons, including: Female mosquitoes spin around people’s heads, wanting to get carbon dioxide, but what makes them attracted to one person without the other, are: the smell of sweat and body temperature, especially because mosquitoes are attracted to strong body odor, as they have their own wide-range sensors It helps her in the process of searching in various places and with it she can reach food more easily.
Mosquitoes are more attracted to people who return from exercising, because these people have made a great effort and therefore their sweat smell is pungent and contains octenol, which is what attracts mosquitoes to them.
Mosquitoes may buzz around people’s ears because they are mating, which is usually done at the human head where there is a swarm of male mosquitoes targeting one female orbiting around the human head.
Other causes of that annoying sound near your ears, and how to avoid it, are as follows:
1- They are attracted to earwax.
Mosquitoes are attracted to areas of the body that smell bad, and when we sleep, we usually cover our bodies with a blanket, leaving our faces uncovered, and ears are one of the dirtiest parts of the body, which may be why mosquitoes want to fly over them.
2- The sound is made of its wings:
Although it sounds like an annoying song, mosquitoes do not sing in your ears, as the sound is produced by the rapid flapping of their wings, which reaches a speed of 250 movements per second, and it has also been found that mosquitoes communicate with each other by making sounds and can Also a “dual mating” configuration.
3- Attracted by your body heat:
Female mosquitoes are looking for food to develop their eggs, so they try to detect human body heat and sweat, which is another reason we can hear them buzzing near our ears.
Here’s how you can ensure a restful sleep:
It is best to wear light-coloured clothes to sleep because mosquitoes are attracted to dark colors.
Take a shower before bed to avoid sweating.
Sleeping under a fast-moving fan.
Put plants like lavender, rosemary, and catnip in your room, as these plants are natural mosquito repellents.
The spread of mosquitoes is frequent throughout the summer, and this makes some people feel uncomfortable and unable to sleep; Because of their buzzing in the ear, why do mosquitoes make this particular noise near the ear?
The buzzing that people hear is often just a side effect of mosquitoes striking their wings in flight, says Michael Riel, a professor of entomology at the University of Arizona. at a frequency of 450 to 500 Hz.
He added that most of the mosquitoes that disturb humans are female, because the lives of males are very different; As they prefer to live near flowers because of the nectar, and therefore do not care about being inside homes or next to humans, unlike the female who is looking for a blood meal after mating to obtain enough energy to produce eggs, according to the American “Live Science” website for science.
He explained that mosquitoes are attracted to humans and fly around their heads due to their attraction to the carbon dioxide that is emitted by the human body, and they head towards the head; It is one of the most common places through which the body expels carbon dioxide.
He stressed that the mosquito, after passing several times at a person’s ear and head, measures his body temperature, and then stands on any exposed part of his skin; To make sure through the sensors in her feet that it is a human being and not an animal, and then start drawing blood after knowing that it is a human; A person’s genes and diet often influence how attractive mosquitoes are to them.
He pointed out that there was a study issued by the “American National Institutes of Health” in 2011, which confirmed that there are certain odors emanating from the skin of some people that cause mosquitoes to be attracted to them.
He said that mosquitoes are strongly attracted to people who have less diverse bacteria on their skin than those who accumulate bacteria, and to people who wear darker colours, especially black.
He stressed that some types of mosquitoes are attracted to bacteria on the feet and not the carbon dioxide released by the body, such as “Anopheles” that transmits malaria parasites, and this explains why mosquitoes are sometimes concentrated around the feet and not the head, and the bites are often concentrated on the feet as well.
And about ways to avoid mosquito bites or its buzz, the professor of entomology advised wearing long and light-colored clothes, and avoiding being in hot places or going to places where there are wetlands.
It is usually noticed that mosquitoes bite some and do not come close to others. What is the secret behind this, and how do mosquitoes distinguish their victims?
According to the scientists, it turned out that the first victims of mosquitoes were people with a specific blood type, because mosquitoes since ancient times have been accustomed to this type, which is the first blood type (A).
People with blood type (B) are, to mosquitoes, “sweets” and they get most allergic reaction from mosquitos, but people with blood type (AB) or (O) do not interest the mosquitoes and are rarely attacked by them.
The carbon gases resulting from the human breathing process also play an important role in mosquitoes choosing their victims, and when a high percentage of these gases are released, the mosquitoes will attack this person, as these insects feel the amount of gases released 50 meters away, according to what was published by Russia Today.
But there is a substance that stimulates the appetite and interest of mosquitoes, which is lactic acid, which is included in the composition of sweat released from the human body, as well as body temperature.
According to the experts from the United States, mosquitoes not only distinguish and sense smells, but can also see, as mosquitoes are interested in bright colors in clothes such as red and blue, but mosquitoes prefer black. Therefore, before you go out to nature, and the places where you are likely to meet with mosquitoes, think carefully about the color of the clothes that you will wear.
