Why did aids do not spread through mosqutos.?

Answer 1

When blood is ingested by a mosquito this is as a food source and so the HIV virus is digested in its stomach. HIV does not replicate within the mosquito body for this reason.
It is true that mosquitos regulate saliva before feeding and some people say that a mosquito putting saliva onto your skin is it flushing out the remains of itslast blood meal into the wound, this is not the case as salivary glands and mouth parts are completely seperate, mosquito feeding mechanisms are highly complex and much more complicated tha a hypodermic syringe like many people think.
In theory if a mosquito was interupted whist feeding on an HIV infected host then moved on to another host with blood still on its needle then transmisson of the HIV virus could occur, also if a mosquito which has fed on an infected host is then squashed by the next host this could smear HIV infected blood onto the skin and into the wound. Both these methods of transmission are possible in THEORY but as the volumes of blood involved are so tiny the probability of this happening is very very small (pobably 1 in millions)

Answer 2

Actually, diseases can be spread via mosquito.

West Nile Virus is a perfect example. Unlike another respondant, mosquitos do leak a minute amount of blood back into the next host. This also goes for anything that draws/injects anything into the body. There will *always* be a tiny amount of backflow.


I think HIV/AIDS is destroyed within the mosquito, however.

Answer 3

Thank god AIDS or HIV is a weak virus and therefore it spreads only through sex contact or through huge transfer of blood from one body to another and does not pass through ordinary kissing or through mosquito bites .

Answer 4

This virus cannot survive in the body of a mosquito. The virus needs a specific environment in which to thrive.

Answer 5

Mosquitoes are only capable of sucking blood out of people, once they have sucked it, it will not leak back out and into another victim of the mosquito.
