can mosquitos transmit aids?
they suck the blood out of other people then suck yours, so can they give you aids or some other kind of disease like that? ive always wondered this! thanks

Why Mosquitoes Cannot Transmit AIDS
by Wayne J. Crans, Associate Research Professor in Entomology
Rutgers Cooperative Extension Fact Sheet # FS736
Media releases concerning the possibility of mosquitoes transmitting AIDS (Acquired Immune Deficiency Syndrome) were common when the disease was first recognized, and the subject is still addressed by tabloids that seek captivating headlines to increase their circulation. The topic was initiated by reports from a small community in southern Florida where preliminary evidence suggested that mosquitoes may have been responsible for the higher on average incidence of AIDS in the local population. The media was quick to publicize claims that mosquitoes were involved in AIDS transmission despite findings of scientific surveys of the National Centers for Disease Control (CDC) that clearly demonstrated that mosquito transmission of AIDS in that community appeared highly unlikely. Nevertheless, media releases perpetuated the concept that mosquitoes transmitted AIDS, and many people still feel that mosquitoes may be responsible for transmission of this infection from one individual to another.
There are three theoretical mechanisms which would allow blood-sucking insects such as mosquitoes to transmit HIV.
1. In the first mechanism, a mosquito would initiate the cycle by feeding on an HIV positive carrier and ingest virus particles with the blood meal. For the virus to be passed on, it would have to survive inside the mosquito, preferably increase in numbers, and then migrate to the mosquito's salivary glands. The infected mosquito would then seek its second blood meal from an uninfected host and transfer the HIV from its salivary glands during the course of the bite. This is the mechanism used by most mosquito-borne parasites, including malaria, yellow fever, dengue, and the encephalitis viruses.
2. In the second mechanism, a mosquito would initiate the cycle by beginning to feed on an HIV carrier and be interrupted after it had successfully drawn blood. Instead of resuming the partial blood meal on its original host, the mosquito would select an AIDS-free person to complete the meal. As it penetrated the skin of the new host, the mosquito would transfer virus particles that were adhering to the mouthparts from the previous meal. This mechanism is not common in mosquito-borne infections, but equine infectious anemia is transmitted to horses by biting flies in this manner.
3. The third theoretical mechanism also involves a mosquito that is interrupted while feeding on an HIV carrier and resumes the partial blood meal on a different individual. In this scenario, however, the AIDS-free host squashes the mosquito as it attempts to feed and smears HIV contaminated blood into the wound. In theory, any of the mosquito-borne viruses could be transmitted in this manner providing the host circulated sufficient virus particles to initiate re-infection by contamination.
Each of these mechanisms has been investigated with a variety of blood sucking insects and the results clearly show that mosquitoes cannot transmit AIDS. News reports on the findings, however, have been confusing, and media interpretation of the results has not been clear. The average person is still not convinced that mosquitoes are not involved in the transmission of a disease that appears in the blood, is passed from person to person and can be contracted by persons that share hypodermic needles. Here are just some of the reasons why the studies showed that mosquitoes cannot transmit AIDS:
Mosquitoes Digest the Virus that Causes AIDS
When a mosquito transmits a disease agent from one person to another, the infectious agent must remain alive inside the mosquito until transfer is completed. If the mosquito digests the parasite, the transmission cycle is terminated and the parasite cannot be passed on to the next host. Successful mosquito-borne parasites have a number of interesting ways to avoid being treated as food. Some are refractory to the digestive enzymes inside the mosquito's stomach; most bore their way out of the stomach as quickly as possible to avoid the powerful digestive enzymes that would quickly eliminate their existence. Malaria parasites survive inside mosquitoes for 9-12 days and actually go through a series of necessary life stages during that period. Encephalitis virus particles survive for 10-25 days inside a mosquito and replicate enormously during the incubation period. Studies with HIV clearly show that the virus responsible for the AIDS infection is regarded as food to the mosquito and is digested along with the blood meal. As a result, mosquitoes that ingest HIV-infected blood digest that blood within 1-2 days and completely destroy any virus particles that could potentially produce a new infection. Since the virus does not survive to reproduce and invade the salivary glands, the mSource(s): http://www.rci.rutgers.edu/~insects/aids.htm

There has been no scientific proof to back up that AIDS can be transmitted through mosquito bites. So the answer is no, but be careful because they still can transmit other diseases like the West Niles Virus.

there has been no scientific records to decrease back up that AIDS could be transmitted by mosquito bites. So the respond isn't any, yet be careful by fact they besides the actual fact which could transmit different ailments like the West Niles Virus.

According to Jonathan F. Day, of the University of Florida's Medical Entomology Laboratory, insects can transmit viruses in two ways, mechanically and biologically. With mechanical transmission, infected blood on the insect's mouthparts might be carried to another host while the blood is still fresh and the virus is still alive. Infection by this means is possible but highly unlikely, because mosquitoes seldom have fresh blood on the outside of their mouthparts.

NO. But they have been transmitting the West Nile Virus. Although this is not comparable to AIDS it can kill you if infected.

Not AIDS, no. Mosquitos do not ingest enough to be a problem, and they certainly don't spit it back out into another person.
Malaria, yes. But that is a bacteria.

NO they dont, well although they such blood there is a certain mechanism not clear scientifically till now that stops the transmission of vatal viruses and bacteria like AIDS and Hepatitis B & CSource(s): I am a Pharmacist

I've never actually heard of mosquitoes transmitting HIV from person to person, but they do trasmit malaria, west nile virus, yellow fever, and many other diseases so I wouldn't rule out the possibility.

Yes I think they can. But that statement could be full wrong. I base it on something I heard a long time ago.
I know for a fact they can give you a whole host of terrible stuff though. (ross river etc…) stay away from them.
