why cant mosquitoes spread AIDS?

Answer 1

Some people argue that the needle-like mouth of the mosquito could lift the virus from one person and inject it into another. This is not possible. The mosquito does not inject blood. The mosquito sucks out blood from a person, and that blood goes into its stomach. When it bites another person, it does not inject the first person’s blood into the second person, but only saliva from its salivary glands. Mosquito saliva does not contain HIV. Unlike malaria, the virus does not develop in the mosquito and is not present in its saliva. HIV only multiplies in human cells.

Answer 2

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:

Answer 3

Even if a mosquito was biologically capable of injecting blood (it's not), and if the mosquito's biological structure could allow an environment in which HIV could not only sustain but thrive (it cannot), the amount of blood along with the stinger being so small (short and thin) and only allowing for a subcutaneous (surface) injection, the amount of HIV-containing blood (it couldn't be much considering the size of a mosquito) would likely not be enough to transmit the virus. HIV, for a lot of people who don't understand the disease and it's transmission is still a pretty scary, so pretty wild theories grow out of the fear.

Being educated about HIV/AIDS is powerful. EDUCATION IS CONTROL AND UNDERSTANDING OF HOW NOT TO BECOME INFECTED WITH THE DISEASE.

Answer 4

Mosquitoes can't spread AIDS because first the virus is HIV. Mosquitoes can't spread HIV because the virus can not survive within the mosquitoe.

Answer 5

I have wonder about the same thing but I think because mosquitos take the blood from you and not deposit it into your blood

Answer 6

NO---this isn't accessible!! The pesky critters do no longer inject blood it receives rid of the blood and it is going immediately to the tummy even as it feeds. even as it feeds on one individual then travels to next sufferer human/animal they do no longer inject the blood they purely took purely saliva this does no longer carry HIV and mosquitoes do not carry It!

Answer 7

because mosquitoes cant have sex with you?

Answer 8

it kills it
