Do Mosquito killing lamps work?
Most users give such products a low rating compared to other products that are used to kill mosquitoes. The reason is that it gives an annoying light at night and its effectiveness is weak in killing mosquitoes. Some users received packages with a defective fan, which is considered a defect in presenting the product to customers. It needs periodic cleaning so that dirt does not affect the efficiency of the lighting. Some users suffer from the fan’s inefficiency in catching insects and not letting them fly again. The lighting is weak even at night, and leaving it alone in the house illuminates the whole house, but does not kill insects at all.
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.
Many are bitten by animals, and the bite can cause a minor wound, but it can be accompanied by serious complications. One of the most serious complications of bites is rabies, or rabies. So you should know what to do when bitten.
Studies have revealed that the human bite is the second most common bite in emergency rooms, and it may be more dangerous than the bite of some predators, and the reason for this is due to the types of bacteria and viruses present in the human mouth. The human mouth contains millions of microbes that coexist inside the mouth between the teeth and gum pockets, and turn into harmful microbes by transferring them to other tissues through biting.
The most common pathogens associated with bite wounds are Streptococcus species, Staphylococcus species, Pasteurella multocida, Capnocytophaga canimorsus and anaerobic bacteria.
Sporadically other pathogens are isolated from bite wounds. Human bites differ from animal bites by higher prevalence of Staphylococcus aureus and Eikenella corrodens.
Infected human bites yield a similar spectrum of bacteria except for Pasteurellae and C. canimorsus; instead human bites are frequently complicated by Eikenella corrodens.When does the Allergic Reaction Appear?
What is the definition of Eikenella corrodens?
Eikenella corrodens is a Gram-negative facultative anaerobic bacillus that can cause severe invasive disease in humans.
E. corrodens is a rare pericarditis associated pathogen.
It is a fastidious, slow growing, human commensal bacillus, capable of acting as an opportunistic pathogen and causing abscesses in several anatomical sites, including the liver, lung, spleen, and submandibular region.
E. corrodens could independently cause serious infection in both immunocompetent and immunocompromised hosts
Eikenella corrodens, a gram negative rod, was cultured in about one third of 24 patients with human bite wounds. The organism was sensitive to penicillin but not to methicillin. Clinically the infections in which Eikenella corrodens were found were not different from other infections.
Most of patients in this series required surgical drainage. Surgical treatment consists of thorough exploration, exteriorization and excision of devitalized tissues. Complications were more frequent in sutured wounds, or when surgical drainage was delayed.
Human bites: Children are more susceptible to this type of bite, as a result of playing with an aggressive child. The bite is semi-circular, or oval, and red. It may leave bruises or holes in the place of the teeth. These bites are often on the face, upper extremities, or trunk.
Dog bites: often happen to children, and the most famous places for bites are the head and neck. In adults, the places of bites are often in the arms and legs, especially the right hand. Injuries range from scrapes, deep open wounds, and lacerations, and dog bites rarely lead to death.
are frequently located on the face; injuries inflicted by dogs are most common, especially in children. Bacteriology of infected dog and cat bite wounds includes Pasteurella multocida, Staphylococcus aureus, viridans streptococci, Capnocytophaga canimorsus, and oral anaerobes.
Cats injury: is often to the upper extremities, such as: the arms, hands, or the face. Deep wounds are a concern; Because cats have long and sharp teeth; So it is possible for bacteria to reach the bone, or joint, leading to inflammation. If infection occurs, it causes redness, swelling, and severe pain as quickly as 12 to 24 hours after the bite.
Rodent bites: The most famous of these are mice, and bites occur at night, often on the hands or face.
Antibiotic therapy against E. corrodens bacteria
It is indicated both for infected bite wounds and fresh wounds considered at risk for infection.
E. corrodens infections of the head and neck occur most frequently in the tonsil even in hosts with normal immunity. Coexistence with Streptococcus milleri group bacteria and the use of ineffective antibiotics can be exacerbating factors. First-choice drugs for E. corrodens infections should be third-generation cephems, carbapenems, or new quinolones.
Amoxicillin-clavulanate (and other combinations of extended-spectrum penicillins with beta-lactamase inhibitors) and moxifloxacin offer the best in vitro coverage of the pathogenic flora. Initial wound management consisting in irrigation and debridement is at least equally important with antibiotics for prevention of infection.
Successful antibiotic therapy
It can be achieved with benzylpenicillin or ampicillin which are the drugs of choice. E. corrodens is a slow growing bacterium of low virulence, rarely isolated in current practice because of its unusual association with conditions such as human bites, infections of the oral cavity or immuno-suppressive therapy.
The lifetime risk of experiencing a bite wound, human or animal, is approximately 50%, and bite wounds account for approximately 1% of all visits to emergency departments. The majority of bite wounds are inflicted by dogs and cats.
The need for prophylaxis against systemic infectious complications
particularly tetanus, should also be evaluated. Primary surgical repair is the treatment of choice for most clinically uninfected facial bite wounds, whereas delayed closure should be reserved for certain high risk or already infected wounds.
It is important to be aware of the possibility of complicating infections following bite wounds, particularly after cat bites.
Clinicians must have a high index of suspicion when evaluating any hand injury and clenched fist injuries of the hand should be treated by early adequate surgical debridement followed by IV penicillin given until operative cultures confirm or deny contamination with Eikenella corrodens.
Treatment of infections associated with cat and dog bites
Phenoxymethyl penicillin should be the drug of choice in treatment of infections associated with cat and dog bites. However, in case of slow recovery or no improvement, simultaneous lymphadenopathy or pneumonia, S. aureus or Francisella tularensis should be suspected; ciprofloxacin is recommended. For human bite infections the recommend treatment is phenoxymethyl penicillin in combination with penicillinase-stable penicillin.
Avulsive injuries with significant tissue loss represent the most difficult cases for definitive management and are also those most likely to require hospitalization.
a prospective study with serial aerobic, anaerobic, and 10% CO(2) cultures is needed to confirm these findings. Lack of organization in management was the most notable finding. Inpatient therapy with intravenous antibiotics usually is required. Treatment should revolve around the mnemonic ‘ODD BITES’: open treatment; debridement; drugs (antibiotics); bloodwork (leukocyte count); irrigation; tetanus prophylaxis; exploration (including X-rays); and swab (for culture and sensitivity).
It is estimated that 250,000 human bites occur each year in the United States, mostly in children. Up to 25% of these infections are contaminated, indicating that the most feared diseases are hepatitis B and tetanus.
Although these diseases do not occur with every bite, hepatitis and tetanus may occur, especially in infected bites.
Complications of infection
The bite may cause complications such as infection, permanent disability or even amputation in some cases. The reason to saliva, which contains millions of bacteria that can cause infection, in addition to the hand itself and the microbes it may contain.
Professor Stephen Kennedy of the University of Washington in Seattle stated that “hand bite” in particular needs medical care, and it is necessary to take antibiotics to reduce infection and complications that can occur in 30-50% of cases.
Regarding the bite of children, it is less dangerous than adults, because adults can have gingivitis and the mouth contains more bacteria.
Regarding the measures that should be taken if a person is bitten by a person and penetrates the skin, Stop the bleeding by applying pressure to it using a clean cloth, and then wash the wound with water, apply an antibiotic ointment to prevent infection, and then bandage the affected area with a clean bandage.
It is reported that, according to the medical website “health day”, there is new research that reviewed many previous studies, which revealed the need to receive medical care and go to the doctor in case of a bite that causes the penetration of the teeth embedded in the skin of the hand, whether from a human or an animal, in order to prevent possible complications. .
To care for a human bite that has caused a skin wound
Stop bleeding by applying pressure to the wound with a clean, dry cloth
Wash the wound thoroughly with soap and water
Apply a clean bandage
Cover the injured area with a medical non-adhesive bandage
Seek urgent medical attention
Risk of exposure to rabies: Everyone who has been bitten by animals such as: raccoon, fox, wolf bat, needs immediate medical attention, even if the injury is minor; Where these animals may be carriers of rabies.
First Aid for Dealing with Animal and Human Bites:
One of common at home remedies, Washing the wound with soap and water; This reduces the incidence of infection. Provide emergency medical attention such as:
In minor wounds:
Wash the wound carefully.
Apply an antibiotic cream.
Cover the wound with clean gauze.
See the emergency immediately if the wound is red, pain, high body temperature, swelling appears, or if you suspect that the dog was rabid.
In deep wounds:
apply pressure to clean gauze; to stop the bleeding.
When you are unable to stop the bleeding, or if you feel very tired, you should call an ambulance.
Go to the doctor as soon as possible; to examine the wound.
When to see a doctor:
When there is severe bleeding that does not stop after pressing on it for 15 minutes, or a feeling of severe pain.
When you notice a rise in body temperature, or when the wound is red, pain, or swelling appears.
If the bite is deep, and it has been five years since the last tetanus vaccination.
If the bite wound is large.
If the patient suffers from diabetes, liver disease, cancer, a weak immune system.
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.
Mosquitoes distinguish ‘dangerous’ people Despite their small size, these mischievous flying insects seem to be more intelligent than we might expect.
According to a recent study published by the newspaper “Current Biology”, a mosquito that is exposed to an attempt to kill a person, distinguishes the smell of this person and does not attack him again, because it feels that it is a threat to its life.
Previous studies had indicated that mosquitoes have certain preferences when choosing their victims, but the recent study said that these intelligent insects can change their preferences and avoid “dangerous people”.
The researchers came to their discovery by using a machine that simulates the hand movements in which a person tries to catch mosquitoes, while spreading the smell of mice near this machine.
Experimentally, the researchers discovered that mosquitoes associate this life-threatening machine with the smell of mice, and that the insects “learned” to stay away from mice.
But the experiment confirmed that mosquitoes’ association between danger and smell occurs only if the source of the danger to the insects is mammals (mice in this case).
“Once mosquitoes associate certain odors with solitary behaviour, their response to that odor is similar to their response to the most effective repellents,” study co-author biologist Jeff Revell said in a statement.
“Mosquitoes remember these smells for days,” Revell added.
Scientists have succeeded in drawing the first complete map of mosquito immune cells, and found a new type of cell that could have a role in the harmful insect’s ability to deal with malaria.
The researchers said the findings, published in the journal “Science”, could help scientists discover new ways to prevent mosquitoes from spreading the malaria parasite to humans, and to break the chain of transmission.
Malaria affects more than 200 million people worldwide and killed an estimated 405,000 people in 2018, mostly infants and children under the age of five.
Oliver Belker, a molecular infection expert at Sweden’s IMEA University who co-led the study, said: “We discovered a rare type of important new cell, which we called (megasite), which can be a factor in the immune priming, and it appears that it leads to more Immune responses to the Plasmodium parasite.
Belcker’s team explained in the study that the mosquito’s immune system controls how the insect transmits parasites or viruses, but so far, scientists know little about the types of cells.
The team studied the Anopheles gambiae mosquito, which carries malaria, and the Aedes aegypti mosquito, which carries viruses that cause other infectious diseases to humans, such as “dengue fever”, “chikungunya” and “Zika”.
The team analyzed more than 8,500 individual immune cells to see which genes were activated in each cell, and to identify molecular markers for each cell type.
“Mosquitoes seem to have good immunity against parasites such as malaria,” said Sarah Tishman, an expert at Britain’s Wellcome Sanger Institute, who co-authored the study.
It doesn’t has any pain, but it feels like there is a bump when touching it.
A lump not change in size
Lumps due to local infections can lead to boils or abscesses, which aren’t appear in the image.
Redness around the bump is localized and small but intensive which means you’ve scratched a lot and not from the bite itself.
No definite center of the bite, no large biting area, no swollen edges, which exclude mosquito bites and fleas bites as well.
It can be due to local allergic reaction due to rash or any benign reason, or may be an ant.
local anti-histamines injection or pills.
A rash is an area of the skin that is inflamed and irritated. Most people are exposed to a rash at some point in their lives. In most cases, the rash is not life-threatening, but rather a transient condition.
In rare cases, a rash can be a sign of a life-threatening condition. Even rashes in children are very common, and most rashes are not of health importance.
When should a doctor be consulted?
There are cases in which you should go to consult a doctor:
If the rash does not respond to home remedies.
When the rash spreads to large parts of the body and appears in areas such as the groin, eyes, and feet.
When the child suffers from an urgent and constant urge to scratch.
When signs of a local infection appear, including redness, swelling, pain when touching the area, and local heat.
If you know that the cause of the rash is taking a new drug or being bitten by animals.
When one of these symptoms appears: fever, difficulty breathing or wheezing when breathing.
The rash can appear anywhere on the body. The rash may be localized or spread throughout the body, as a rash that is widespread throughout the body is often the result of a viral infection or an allergic reaction.
The main symptoms of rashes
The area of the rash is usually warm and sensitive, and symptoms include:
desire to scratch
Specific swelling and characteristic skin lesions.
Cracks in the skin
Various cutaneous lesions of the skin.
The appearance of crusts in the area of the rash
Fluid secretion in the area of the rash
Symptoms of a rash that indicate a medical condition
Additional signs of important medical conditions include:
Excessive sensitivity to touch the affected area.
shortness of breath.
Pain or a feeling of choking in the throat.
Red streaks spread from the rash area.
Causes and risk factors for rashes
If a relative of the patient suffers from allergies or asthma, this makes the patient more likely to develop a rash. In addition, people who spend a lot of time outdoors in nature are more likely to develop a rash as a result of exposure to irritating plants such as nettle or insect stings.
Common causes of rashes
Common causes of a rash include:
Allergic reaction due to an allergy to animals, an allergy to a variety of medicines, or an allergy to food.
Side effects of various medications.
Excessive abrasion of the skin as a result of strenuous activity while wearing ill-fitting clothing.
Parasitic infections such as scabies .
Constant exposure to heat, moisture, and irritants such as diaper rash.
Diseases that cause rashes
Among the diseases that can cause the appearance of a rash:
Acne: It often appears on the face, neck and back.
Lupus erythematosus: a butterfly-shaped rash on the cheeks and upper nose .
Lyme disease: It is a disease with a characteristic rash, circular in shape, similar to a disc on the target.
Psoriasis: is the infection of certain areas with clear borders covered by scales called plaques.
Skin rash complications
A rash that is not treated may cause the following:
It creates a suitable environment for viral and bacterial infection It causes open sores that may become infected.
Diagnosis of the rash
The rash may be diagnosed by:
Do a blood test .
A biopsy of the rash was taken and analyzed.
Ask the patient if he is allergic to a particular drug or food.
Examine the shape and appearance of the rash and ask about symptoms associated with it.
Skin rash treatment
The treatment of rashes is adapted to the type of rash and the diagnosis reached. The treatment is carried out as follows:
The rash caused by a viral infection is transient in that it resolves on its own within a few days or weeks without requiring drug therapy.
Anti-itch medicines and aloe vera ointments can be used to relieve itching.
In cases of rash worsened by exposure to cold and dry air, moisturizing creams can be used, and sometimes medical ointments containing steroids should be used.
Addresses the rash caused by inflammation by ointments antibiotics or taking antibiotics by mouth or by anti-fungal. If topical ointments fail to treat the rash, a steroid pill is sometimes needed, which can relieve symptoms more effectively.
Prevention of rashes
In order to prevent simple rashes, the following should be followed:
Keeping hands and nails clean.
Avoid exposure to irritants.
Use of safe products that do not cause allergies .
Reducing the phenomenon of itching to prevent secondary infection in the affected area.
Woke up with these 9-10 bites on my left foot this morning… I’m guessing chiggers or fire ants… anyone else?
By analyzing these images, we can find:
multiple bites at the same leg not single
raised bumps and not flat
welts formed and filled with pus
sprinkled blisters not on the same line
Fire ants leave bites that is hive-like lesions with central pustule formation during 24 hours, and the fire ant bite size is smaller than chigger’s bite size.
Fire ants may bite one single bite at specific site especially extremities, but the chiggers cause several stings at once in different locations on skin either as multiple bites in one line or sprinkled bites.
Woke up with pain on my back. Husband took a picture. He says it looks like a huge pimple, but the middle is hollow and red. Anyone know what bit me in Maryland?
Lets describe the bite appearance as seen in the image:
the puncture is single, big and has no definite edges as known spider or tick bites
looks deeper and wider than most common insect bites
it’s similar to pustules especially on the back.
abscess that grown and squashed somewhat then left that manifestation, tell your husband to touch it carefully with a sterile cotton or some kind of a plastic tool if inflammatory liquor identified, then it certainly a pustule, treatment can be a proper antiseptic.
Spider bite or another insect bite that developed into abscess, also antiseptics can resolve it but with proper identification as said.
