y mosquito do not spread aids to man?

Answer 1

Here is what your looking for:
Mosquitoes, when they bit a human and obtain blood they do not "spit" or "regurgitate" another person's blood into someone else. Malaria, on the other hand, is spread because we know that the developing parasite livesin the moquito and makes its way into the saliva which does get transmitted during a bite...

Answer 2

I always wondreed that too because what if they bite someone who is infected with the virus then bite someone else isn't that blood to blood contact? MERRY X-MAS!!!!!!!!
