Can Mosquitoes Transmit HIV or AIDS?
Mosquitoes are infamous for passing on dangerous diseases to humans, particularly in tropical and subtropical climates. This is because they are able to harbor diseases that they contract from biting infected animals. So, what happens when a mosquito bites an HIV-positive person? Thankfully, mosquitoes are unable to transmit HIV or AIDS. This is because of the makeup of both the virus and of the mosquito.
- Mosquitoes cannot become infected with HIV, so they cannot pass it on.
- Since mosquitoes’ proboscises have two tubes, one that takes blood and one that distributes saliva, there is no chance of HIV being passed from mosquito to host. HIV remains in the blood.
- The virus disappears in the mosquito’s body after about two days, so even if a mosquito with HIV bit a human, the virus wouldn’t replicate enough to infect anyone.
Do Mosquitoes Transfer Blood to People?
Although mosquitoes take blood from humans, they don’t circulate any back into the people they bite. This is due to the structure of their proboscis. It is made up of two tubes, one that transmits saliva and one that draws blood. This two-tube system is the reason that mosquitoes cannot pass on HIV, even when they ingest infected blood. Any amount of the virus contracted by a mosquito will die in its digestive system.

How Long Does HIV Last Inside a Mosquito?
When a mosquito bites someone who is infected with HIV, the contracted virus will dissipate within two days. HIV is unable to replicate inside the mosquito’s digestive system, unlike humans, in which it binds to T cells. As the mosquito digests the blood to process the nutrients it contains, any virus particles will be destroyed.
Have Mosquitoes Ever Been Able to Transmit HIV?
The bottom line is that you should not be concerned about contracting HIV from a mosquito bite. Because of the nature of the virus and the structure of the mosquito’s body, it is impossible for any foreign blood to make it back into your bloodstream. When it comes to learning about mosquitoes and the diseases that they’re associated with, it’s important to focus on the dangerous diseases that they have been proven to spread.
