AIDS spreads from infected syringe but if a mosquito bites after biting infected person it does not spreadswhy

Answer 1

There is actually no conclusive empirical evidence that the HIV virus cannot be spread by the mosquito vector.

Answer 2

hypothetically this is actually a possibility.
However, HIV, as nasty as it is, has a short half life outside of the body. Hepatitus by contrast can exist much longer, as can TB. So the blood surrounding the mosquitos "chops" probably no longer carries HIV when the mosquitos becomes hungry and eats again.

However, it is an interesting question... and often I wonder about the pathology of the disease and if doctors are being truthful with us when they trace the line upon discovering a persons status.

It's seems a little haphazzard to me sometimes.

Answer 3

No. When a mosquito ingests HIV-infected blood, the virus dies (unlike malaria, which lives in the mosquito's intestinal system and is re-injected out in its oral fluid). The mechanical procedure of feeding wipes blood off of the mosquito's proboscis--it is retracted into a sheath. Even in geographical areas where mosquitoes proliferate, HIV is still seen only in sexual or blood-sharing adults.

Answer 4

I am not quite sute but maybe because mosquitoes have a type of immunity to the disease which makes its saliva immune to the disease so when it bites a human, the human will not be affected. Or maybe (going a little hippie) God didn't plan it to happen, as many people would die due to mosquitoes, many die already from malaria, if AIDS was mixed in thousands of millions of people would die.

Answer 5

HIV does not reproduce easily outside the human body and cant survive in the saliva of insects. HIV s an intelligent virus. It can mutate and hide inside the body, which makes it an almost invincible target. However, outside the human body, the virus s weak n cant be sustained.

Answer 6

When a mosquito bites it injects an anti coagulant to prevent his beak[proboscis] from getting stuck,the chemical kills hiv.

Answer 7

HIV an infection isn't unfold by casual touch jointly with hugging, by touching products earlier touched by someone contaminated with the virus, for the time of participation in activities, or "by mosquitoes". Please see the webpages for extra info on AIDS.

Answer 8

There has been extensive research on this and the answer is that our flying friends do not spread aids

Answer 9

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 mechanism that most mosquito-borne parasites use to get from one host to the next is not possible with HIV.
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.
Mosquitoes Are Not Flying Hypodermic Needles

Many 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.
