Can Mosquitoes Transmit HIV or AIDS?

Because mosquitoes feed on blood and are known to transmit dangerous diseases, there is a lot of fear about whether they’re able to transmit HIV. Even if they bite an HIV-positive individual, mosquitoes cannot transmit HIV or AIDS. This is due to both the biology of the mosquito and of HIV itself:

  • Mosquitoes are unable to become infected with HIV, and thus cannot transmit it.
  • A mosquito’s proboscis 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 a host, there would not be enough to infect. The virus disappears in the mosquito after just one or two days.

Do Mosquitoes Transfer Blood To You?

Mosquitoes may suck blood, but they do not inject blood or circulate it back inside of you in doing so. This is due to their unique proboscis that consists of two tubes. One of the tubes 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.

Can Mosquitoes Carry HIV?

If and when mosquitoes feed on HIV-positive people, it will not stay in their system for long. The virus will disappear in just 1-2 days, which is the time required for a mosquito to digest the blood. In human beings, HIV replicates by binding to T cells. In a mosquito’s gut, the HIV is incapable of replicating and is thus destroyed in a short amount of time.

Is There Proof of Mosquitoes Transmitting HIV?

There is no reason to worry about mosquitoes transmitting HIV or AIDS. 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. Though they don’t transmit HIV, it’s important to focus on the vector-borne diseases mosquitoes do carry and spread to people.
