Why can’t mosquitos transmit HIV to humans?

173 viewsBiologyOther

I’ve long known that mosquitos cannot transmit HIV to human beings, but has anyone ever considered this theory?

If an HIV infected person was standing beside of an HIV negative person, and a mosquito flys over and bites the HIV positive person, and then seconds later, that exact same mosquito flys over to the HIV negative person and begins to bite them. Why can’t the HIV positive blood remain infectious on the mouthparts (needle, feeding apparatus) of the mosquito and infect the HIV negative person? Think of it like a flying hypodermic needle/syringe! Keep in mind, only a few seconds have passed between the two bites. Let’s hear it!

That is an extremely minute amount of blood.

The mosquito also immediately pulls all the blood into its gut and prior to biting someone else, prepares saliva in its Stylets then injects that before pulling out blood. Therefore there is no remaining blood within its Stylets.

Also mosquitos don’t have T cells therefore the virus can’t replicate.
