Answer 1

There are 3 key factors.

1. Mosquitos don’t inject blood into people when they bite, they suck blood out. They DO inject saliva, but in tiny amounts
2. HIV can’t survive in a mosquito
3. Even if they could inject blood into you, the amount they do wouldn’t contain nearly enough of the HIV virus for you to develop the disease.
