How does it survive the transfer to a syringe needle and then to someone else?
If a mosquito bites someone and less than a minute later it bites me how is that different than the syringe?
Is the mosquito magical in some way?

The HIV retrovirus survives in certain biospheric conditions favorable to the virus, but it is destroyed by common agents outside its favorable biosphere such as ultraviolet light, Oxygen, and so forth. The syrings needle may in isolated instances provide enough Human proteins and protection from the general environment for its survival until it can be introduced into another Human biosphere. Insects lack the unique Human proteins necessary for the HIV retrovirus to find protection from the general environment. This is why HIV is generally a sexually transmitted disease and direct Human or primate bloodborne retrovirus. Expose the HIV retrovirus to a non-Human biosphere and non-himan proteins and you destroy the organism.
