The human immunodeficiency virus (HIV) can be transmitted via unsterilized objects, blood transfusion, and some other blood/fluid related substances. From the mosquito perspective, the vector sucks blood and may instantly suck that of another. Supposing it sucks a HIV carrier and immediately sucks another person (A non HIV carrier). Will the HIV be transmitted or what would happen to the non-carrier? Or is there a substance that would hinder the transmission of the VIRUS?
