Why do mosquitoes carry West Nile and other viruses, but not HIV?
gpt
HIV doesn't reproduce in insects. When the mosquito bites you, it injects it's saliva, not its own blood or the blood of previous bite victims. Since HIV doesn't reproduce in insects, it's not transmitted via saliva unlike malaria or yellow fever. Plus, it usually takes a while to digest the blood after they sucked it out of you. They don't go from person to person sucking blood like a chinese buffet.
