Do Mosquito Insect Bites Transmit Virus B and C?

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.

  1. Mosquitoes inject people with their own saliva, not blood. Thus induce allergic skeeter syndrome
  2. It is known that Virus B and Virus C infections are transmitted through exposure to blood only.
  3. 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
  4. 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.
  5. 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.
  6. 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.
  7. 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.

Dengue fever

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.

Yellow fever

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.

Chikungunya disease

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

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.
