This question has been asked for years, and the answer is no. Mosquitoes cannot become infected with HIV and thus cannot transfer it. A mosquito’s proboscis has two tubes: one to suck blood from its host and the other to inject saliva into the host. The saliva contains anticoagulants that help keep the blood flowing. Still, it does not have enough of the virus particles necessary for the transmission of HIV.
In addition, mosquitoes lack the receptor HIV uses to recognize immune cells. This means that even if a mosquito could acquire an HIV infection, it could not spread it further.
It is important to note that while mosquitoes cannot transmit HIV, they can still spread other infections, such as malaria and dengue fever. Therefore, taking precautions against mosquito bites is important to reduce your risk of contracting these illnesses.
