Can Mosquitoes Transmit HIV or AIDS?
We all know mosquitoes can transmit some of the world’s most dangerous diseases. Mosquitoes are actually vectors for diseases that they typically get from biting infected people or animals. With this being the case, what happens when a mosquito bites someone who is HIV-positive? Thankfully, mosquitoes are incapable of transmitting HIV or AIDS. This is in part due to the unique biology of a mosquito:
- Mosquitoes are unable to become infected with HIV, and thus cannot transmit it.
- The proboscis of a mosquito has two tubes: one to suck blood from its host and the other to inject saliva into the bite. Because only saliva is injected into the host, HIV cannot be transmitted through the bite.
- Even if a mosquito has HIV in its body when it bites someone, there would not be enough of the virus present to infect that person. The virus disappears in the mosquito after just one or two days.
Do Mosquitoes Inject Blood Into You?
Mosquitoes may be blood suckers, but do they inject any blood back into you during the process? Thankfully, no—the unique biology of a mosquito disables them from doing so. Made up of two tubes, one tube of their needle-like proboscis sends saliva into the host while the other sucks up blood. This two-tube system is why mosquitoes cannot transmit HIV, which is transmitted through infected blood. Any HIV-positive blood ingested by a mosquito is thus impossible to transmit to another host.

Do Mosquitoes Carry HIV?
If a mosquito bites someone who is HIV-positive, the virus will disappear in just 1–2 days, which is the time required for a mosquito to digest the blood. This is because HIV is unable to replicate within the mosquito’s gut, unlike humans in which HIV binds to T cells. It is during the mosquito’s digestion process that any HIV ingested is completely destroyed.
Can I Get HIV From an Infected Pest?
Thankfully, you do not need to worry about mosquitoes ever transmitting HIV. Research has proven that an individual would have to be bitten by 10 million mosquitoes that all had been feeding on an HIV carrier for even a single unit of HIV to be transmitted. When it comes to mosquitoes and diseases, it’s important to stay aware of the few diseases they are capable of spreading throughout communities.
