The virus is able to recognize and bind to “anchors” or markers expressed on the surface of these cells, known as CD4 receptors. These cells are essential for the proper functioning of the immune system.
In humans, the targets of HIV are mainly T-helper T cells, monocytes, macrophages, and dendritic cells. Hepatitis C virus and HIV, on the other hand, are much more “sophisticated”: they only infect some very specific cell types that are not found in all species. This is the case with the Zika or Chikungunya viruses. Moreover, not all viruses are the same: some viruses penetrate and multiply more easily into cells than others.

It must then reach the cells of the intestinal wall and find an anchor point to penetrate and multiply in the cells, which is not without problems.Īfter the viral load (i.e. In fact, once a virus has been ingested during a blood meal, it must resist the hostile environment in the mosquito’s intestines (acidity, digestive enzymes…). Transmission of viruses through Mosquitos not so easy In fact, it is a little more complicated than that. You may think that if an insect ingests a virus from an infected person during a blood meal, it can pass it on to a healthy person at the next meal. Firstly, it is not so easy for a virus to spread through mosquitoes, whether HIV or not. Unlike the Zika virus or malaria parasites, HIV cannot be transmitted to humans by mosquitoes.

However, on certain online platforms and social networks, the topic is still regularly discussed. It is impossible to become infected with the Human Immunodeficiency Virus (HIV) through a mosquito bite.
