Can Mosquitoes Transmit HIV or AIDS?
As blood-sucking insects, it’s easy to see why some people may be worried about mosquitoes transmitting HIV or AIDs. However, this is not a possibility, even when mosquitoes feed on an infected person. Here’s why:
- 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.
- In the rare case 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.
