its a shame we cant breed genetically modified mosquitoes to spread anti virul vacines around the world.
HIV is the virus that causes AIDS, the syndrome. I'm sure I remember some research into using mosquitos to spread something, or maybe it was about releasing sterile ones into the wild so that they'd breed but not produce baby mosquitos, or something. I don't know. maybe I'm confused.
Mosquitoes Are Not Flying Hypodermic NeedlesMany people think of mosquitoes as tiny, flying hypodermic syringes, and if hypodermic needles can successfully transmit HIV from one individual to another then mosquitoes ought to be able to do the same. We have already seen that HIV-infected individuals do not circulate enough virus particles to result in infection by contamination. However, even if HIV-positive individuals did circulate high levels of virus, mosquitoes could not transmit the virus by the methods that are employed in used syringes. Most people have heard that mosquitoes regurgitate saliva before they feed, but are unaware that the food canal and salivary canal are separate passageways in the mosquito. The mosquito's feeding apparatus is an extremely complicated structure that is totally unlike the crude single-bore syringe. Unlike a syringe, the mosquito delivers salivary fluid through one passage and draws blood up another. As a result, the food canal is not flushed out like a used needle, and blood flow is always unidirectional. The mechanics involved in mosquito feeding are totally unlike the mechanisms employed by the drug user's needles. In short, mosquitoes are not flying hypodermic needles and a mosquito that disgorges saliva into your body is not flushing out the remnants of its last blood meal.For more in depth information on this topic see Staff Paper #I, Do Insects Transmit AIDS?, OTA series on AIDS-Related Issues, Health Program, Office of Technology Assessment, United States Congress, Washington, D.C. 20510-8025.
LO..Yes, it is interesting isn't it ?
So, how come mosquitos can transmit other viruses like the West Nile Virus?There's got to be something in mosquitos that kills the HIV virus.Or, as some suggested, the HIV must be injected en masse. Doesn't make sense to me.
These facts are confirmed by looking at infection patterns. In areas where mosquitoes are common and where HIV is prevalent, the distribution of AIDS cases in the population is not different from other areas. If mosquitoes transmitted HIV, they would be seeing a disproportionate number of children and elderly infected in those areas.
i suspect that the HIV virus in human blood, when aspirated by the mosquito gets disrupted as the virus was very host specific and also the mosquito takes some time for next feed, so, the viruses may be killed, as the virus will be alive for very few second outside the host (primates). too, mosquitoes will never inject the aspirated blood.
This is a resounding NO, they cant spread HIV . This virus is only spread via exchange in bodily fluids. Mosquittos are vectors for other viruses such as Maleria.
Anyway there's a nice summary on this page of many reasons why mosquitoes are not transmitters of AIDS...sorry, you cannot view external links. To see them, please
