Thats a good question. I also want to know why is it attempted murder if you spit at a cop? I thought the HIV and AIDS virus dies when exposed to oxygen, so how can AIDS be passed on by spit?

Mosquitoes are very good vectors for transmitting disease generally. The female mosquito requires a blood meal in order to be able to lay her eggs. Male mosquitoes do not require a blood meal and feed on plant nectar and the like, as do females for a source of sugar for flight fuel requirements. While people know that malaria (a parasitic protozoan) is transmitted by mosquitoes, malaria actually uses the mosquito for part of its own life cycle. When a mosquito has a blood meal from someone with HIV, any virus that is consumed is actually digested within the gut of the mosquito and therefore not able to be transmitted to the next victim of that mosquito. On the other hand, the virus that causes yellow fever can multiply inside of the mosquito and survive. When a mosquito bites, it injects saliva, with an anti-coagulant contained within it, from a specific tube of its "mouth parts". When it feeds on the blood, the blood is siphoned up through a different tube. So the tube that handles blood uptake is entirely separate from the one that injects saliva.

No. From the start of the HIV epidemic there has been concern about HIV transmission from biting and bloodsucking insects, such as mosquitoes. However, studies conducted by the CDC and elsewhere have shown no evidence of HIV transmission from mosquitoes or any other insects - even in areas where there are many cases of AIDS and large populations of mosquitoes. Lack of such outbreaks, despite intense efforts to detect them, supports the conclusion that HIV is not transmitted by insects.

The results of experiments and observations of insect biting behavior indicate that when an insect bites a person, it does not inject its own or a previously bitten person's or animal's blood into the next person bitten. Rather, it injects saliva, which acts as a lubricant so the insect can feed efficiently. Diseases such as yellow fever and malaria are transmitted through the saliva of specific species of mosquitoes. However, HIV lives for only a short time inside an insect and, unlike organisms that are transmitted via insect bites, HIV does not reproduce (and does not survive) in insects. Thus, even if the virus enters a mosquito or another insect, the insect does not become infected and cannot transmit HIV to the next human it bites.

There also is no reason to fear that a mosquito or other insect could transmit HIV from one person to another through HIV-infected blood left on its mouth parts. Several reasons help explain why this is so. First, infected people do not have constantly high levels of HIV in their blood streams. Second, insect mouth parts retain only very small amounts of blood on their surfaces. Finally, scientists who study insects have determined that biting insects normally do not travel from one person to the next immediately after ingesting blood. Rather, they fly to a resting place to digest the blood meal.

When mosquitoes bite a person, they do not inject the blood of a previous victim into the person they bite next. Mosquitoes do, however, inject saliva into their victims, which may carry diseases such as dengue fever, malaria, yellow fever or the West Nile virus, thus infecting the person being bitten. However, HIV is not transmitted this way. On the other hand, a mosquito may have HIV-infected blood in its gut, and if swatted on the skin of a human who then scratches it, transmission may occur. This risk is very small, and no cases have yet been identified through this route.

Mosquitoes have the power to digest HIV virus

HIV is a fragile virus outside of it's host if I remember the time right it's like 8 seconds outside of the body mosquitos thankfully aren't vectors (carriers) of it because of there nature and the virus not being compatible

To be honest with you. no of researches gives a proved explanation for your raised Q.

Actually to provide you: theoretically HIV has it ability to live on mosquitoes! BUT THAT WHAT DON"T HAPPEN

Mosquitoes blood bladder contains formic acid which destroys the virus.

because mosquitoes dint keep blood in their body for long they just vomit it and go get some more blood.
