why mosquito doesnot spread AIDS (as they suck blood frm one person and bites to another person)?

HIV is very specific about where it can live. HIV thrives in human cytotoxic T cells. It can sort of live in the T cells of other higher primates, which is why we can use monkeys in hIV research.\n\nHOWEVER, HIV can't live in the digestive tract of a mosquito. For one thing, it's a mosquito: not the right environment for HIV to splice in, replicate and proliferate. Secondly, it's a digestive tract. It has enzymes that can kill the virus particles.\n\nSo that's why mosquitoes can't transmit HIV.

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.

Hi buddy,\n\nThe HIV virus is a very fragile virus that gets easily killed on drying or contact with ordinary toilet soap or even very dilute spirit.The world wide fear of this infection is not because it gets easily transmitted or that its a tough virus to kill.Its just because the virus attacks the patient's immune system. Death in an HIV infected person comes in the form of other diseases that attack the person when his body's defence mechanisms are in a weak state.\n Human saliva is not demonstrated by research to contain enough load of virus as to cause infection to another person ingesting it. There is a theoretical possibility of the virus getting transmitted thru deep kissing, if the kisser has a mouth ulcer. The virus in that case has a (very small) chance to enter the body of the individual thru this open wound in the mouth. Still the virus may not survive the variable pH levels and salt concentrations of the human saliva.   And all the more, the probability of this type of  transmission is less than 0.01% . In day to day life that kind of probability is considered as ZERO chance...!  Hence we, healthcare workers don't consider saliva as a potential source of infection. Like wise, the chance of a mosquito transmitting the virus is somewhere near 0.004%..!!\n\nRegarding Web sources on AIDS, the United Nations' website is the ultimate knowledge bank ... Log on to www.unaids.org and find a wealth of info and links.\nAll the best.\nBye.

lol they do not exist but i am sure they would if they did get  aids. heck they are dead n e ways right so would it matter? i saw this thing on dateline where these freaks go around drinking ppls blood with implanted fangs thinking they are living the life of a vampire. some of them of corse had contracted aids.

did you know that it's only female flies that bite you for your blood?\nmosquitos have very short lives, and the female mosquito uses its short life for the sole purpose of reproducing.\nthey need the blood as energy for her offspring and the nutrients from the blood to reproduce. \ni don't know if other bugs do that, they probably do, as there a lot of bugs in the world that we don't understand. \n\nhope this helps...

without protection for 100% sure the virous will be transmited.but being a hiv possite person doesnt mean that u will get AIDS for sure,there r some ppl who only carry the virus and transmit it to others!

Mosquitoes can ingest up to three times or more than their own body weight in blood. This is normally about 5 microliters.

The mosquito is mearly consuming the blood, whereas people getting transfusions are replaceing their blood with wrong blood and the body is fighting back aginst it.

There is a lowered chance that a person performing oral sex on an AIDS infected man will get AIDS.  HIV (the virus that causes AIDS) is spread through semen, but that infected semen has to get into the blood stream of the other person.  That will only happen if the person giving the oral sex has open sores or wounds in their mouth.  Oral sex is a LOWER risk behavior for HIV infection, but it is still risky.  Use a flavored condom or dental dam anytime you give or receive oral sex.  And remember, there's more than just AIDS out there.

If a disease has an insect or animal vector, the spread of the disease will be controlled by the spread of the vector.  For example, you'd be hard pressed to find malaria in Switzerland, because the climate does not support the type of mosquitoes that carry malaria.  Similarly, we have watched the spread of bird flu from China to the rest of the world along the paths of migrating wildfowl.  Dengue most likely came to the US with mosquitoes inside tires brought here from Asia for recycling.\n\nIf a disease is carried only by humans, then it is spread as humans move.  Even some insect borne diseases are affected by humans.  For example The Black Death (bubonic plague) spread out into Europe from seaports.  It was carried in fleas, on rats, in the holds of ships.  Cholera spread around the world as people with the disease deposited their wastes in places with bad sewer systems.\n\nAIDS is actually two different but very similar diseases which arose in two parts of Africa.  It spread throughout Africa along major routes of human migration.  It is still less common north of the Sahara Desert than south of it.  \n\nAIDS is not really limited be geography because it involves human behaviors of choice.  If I sneeze into my hand and then open a door and you come by a half hour later and touch that door knob and then touch the mucous membranes of your face without washing in between, you will most likely get my cold or flu or whatever.  If I have AIDS, however, you won't catch it.  AIDS is spread by sexual contact and activities where blood moves from person to person, such as sharing needles used for injecting drugs and receiving blood donations (although blood is screened now).  This is why Ebola is still in Africa and AIDS is not.\n\nThe spread of AIDS throughout Africa has more to do with political (war) and socioeconomic conditions that encouraged the mass migrations of people, primarily out of the jungles into the cities.  In addition to bringing diseases into enormous new populations, which would have even encouraged easily transmissable diseases like measles, the behaviors encouraged by having large populations of males without access to women of their own tribes to marry and large populations of women with no way to support themselves besides prostitution really kicked the disease in the butt.\n\nIt's also no accident that in the West, the disease was traced back to Gaetan Dugas, an Air Canada flight attendant.  Although some now dispute this, it is true that Dugas was sexually promiscuous even after he knew he had AIDS and in fact was displaying the tumors of Kaposi's sarcoma.  If anyone could help AIDS cross geographic boundaries, it would be someone who traveled a lot.

only fluid transfer causes aids, i believe saliva doesn't count but dont quote me on that

Plasmodium parasites also undergo stages of development. There is a certain stage in their life cycle that they will have to go to a female mosquito body part to propagate and become the phase that is transmitted to humans through feeding. The same goes true also that female mosquitoes are the ones that bite and feed especially at night.Hope this helps. God bless

It is possible to transmit AIDS by saliva but not very often.  It's more often transmitted by blood or sexually.  AIDS is an STD.  People often transmit it by using already used needles.  It's more likely to be transmitted by kissing if you have an open wound in your mouth, like a cut on your lip.

HIV is a bloodborne, fluid pathogen, That means there must be an exchange of body fluid. example the person with the infection bit u and broke the skin. HIV while the majority of the virus is in the blood stream can and is spread thru other body fluids such as semen, saliva and vaginal fluids of course the other person must have abrasions, cuts, tears in order for the virus to enter their body. Remember even minute microscopic abrasion can let the virus enter your body.\n\nHope that helps and perhaps brings you some peace of mind.\nbest of luck.

You contact HIV usually through unprotected sex, sharing needles, or blood transfusions, basically body fluids and open wounds.  Anyone is at risk for it because people who have it might not know at first and be spreading it to others, the stereotypes are usually hookers, gay people, drug users, street people but that's not really true because anyone can get it or be born with it, we just all like to think it won't happen to us.  Risky behaviors are unprotected sex, sharing needles, and open wounds that bleed and anyone else with an open wound touching something can pick up germs.  It depends on the person as to how long they live.  Some believe saliva can spread germs, others don't. I would just be all around careful if I was around someone I knew that could possibly be infected.

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. \n\n     There are three theoretical mechanisms which would allow blood-sucking insects such as mosquitoes to transmit HIV.\n\n1. 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.\n\n2. 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.\n\n3. 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.\n\n     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:\n\n \n\n  Mosquitoes Digest the Virus that Causes AIDS\n\n\n    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 stom

Mosquitoes can transmit blood born illnesses like yellow fever, so it is wise to be careful but from the government aids fact sheet:  http://www.cdc.gov/hiv/pubs/facts/transmission.htm\n\nSome people fear that HIV might be transmitted in other ways; however, no scientific evidence to support any of these fears has been found. If HIV were being transmitted through other routes (such as through air, water, or insects), the pattern of reported AIDS cases would be much different from what has been observed. For example, if mosquitoes could transmit HIV infection, many more young children and preadolescents would have been diagnosed with AIDS.
