I know everywhere it says that it cant pass such to a human but it can pass the west nile why is that?

I think that is said to stop mass panic.

Maybe you should educate yourself instead of jumping to ignorant conclusions?

There are a great many viruses that cannot be transmitted by mosquitoes. In fact, the vast majority of viruses cannot be transmitted by mosquitoes.

Maybe its because the AIDS virus can no longer sustain itself once inside the mosquito?

Just a guess.

because they are two totally different things?

Why can planes fly but not boats??

mosquitoes do not inject blood when they bite. thus, mosquitoes do not transmit the virus.

west nile is a disease that is carried in the mosquito saliva...the mosquito DOES inject some of that to numb the person it is biting.

okay.... suppose a mosquito ingests some blood, but before its full, it makes a quick get-away to avoid being slapped dead. Then, it lands on another person with an open sore. The second person has faster reflexes and smashed the mosquito dead. How about then, huh?

Unlikely, yes. Impossible? I don't agree.

It's possible that a terrorist could blow up a window near you, causing a cut, and seconds later a bolt of lightning strikes an HIV positive person near you causing him to explode and splatter blood on you.

Epidemiologists>you.

alright, not impossible but an anvil is more likely to fall on one's head:

from the article above:

Mosquitoes Do Not Ingest Enough HIV Particles to Transmit AIDS by Contamination

Insect-borne disease agents that have the ability to be transferred from one individual to the next via contaminated mouthparts must circulate at very high levels in the bloodstream of their host. Transfer by mouthpart contamination requires sufficient infectious particles to initiate a new infection. The exact number of infectious particles varies from one disease to the next. HIV circulates at very low levels in the blood--well below the levels of any of the known mosquito-borne diseases. Infected individuals rarely circulate more that 10 units of HIV, and 70 to 80% of HIV-infected persons have undetectable levels of virus particles in their blood. Calculations with mosquitoes and HIV show that a mosquito that is interrupted while feeding on an HIV carrier circulating 1000 units of HIV has a 1:10 million probability of injecting a single unit of HIV to an AIDS-free recipient. In laymen's terms, an AIDS-free individual would have to be bitten by 10 million mosquitoes that had begun feeding on an AIDS carrier to receive a single unit of HIV from contaminated mosquito mouthparts. Using the same calculations, crushing a fully engorged mosquito containing AIDS positive blood would still not begin to approach the levels needed to initiate infection. In short, mechanical transmission of AIDS by HIV-contaminated mosquitoes appears to be well beyond the limits of probability. Therefore, none of the theoretical mechanisms cited earlier appear to be possible for mosquito transmission of HIV.
