Can Mosquitoes Transmit HIV or AIDS?

Everyone knows that mosquitoes are able to transmit some of the world’s most dangerous diseases. This is because mosquitoes are vectors for diseases that they get from biting an infected human or animal.

So what happens when a mosquito bites someone who is HIV-positive? Thankfully, mosquitoes cannot and have never transmitted HIV or AIDS.

Do Mosquitoes Transmit HIV?

Although mosquitoes suck blood, they do not inject or circulate it back into you. Therefore, they cannot transmit HIV:

  • 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 Carry HIV?

If and when a mosquito bites an HIV-positive individual, the virus will disappear in just 1-2 days, which is the time required for a mosquito to digest the blood. 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. This is another reason why there should be no fear of mosquitoes being able to transmit HIV.

Have Mosquitoes Ever Transmitted HIV?

Mosquitoes cannot and will not transmit 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 focus on the vector-borne diseases they do carry and spread, such as Zika and West Nile.
