why is it difficult to get rid of AIDS virus out the human body?

Actually getting rid of any virus is difficult.  In order for a virus to be destroyed, your body's immune cells need to form antibodies that can specifically identify the virus and cause the virus and all the infected cells be neutralized or killed by other immune cells.\n\nThe problem with HIV is several:\n\nFirst, the protein shell that surrounds the virus and makes it identifiable is constantly changing, so by the time an antibody is formed, it may not recognize the virus any more.\n\nSecond, the virus is a RNA retrovirus, meaning once it infects a cell, it can get itself copied into the DNA of the cell and hide there without detection, sometimes for years.\n\nThird, the cells that the virus likes to attack are the very immune cells that are supposed to be fighting off the virus.  This prevents the whole immune system from working the way it is supposed to and the virus just continues to spread unchecked.\n\nFourth, because it is a virus, normal antibiotics just don't work against it.  And even the anti-virals that have been developed only slow down its ability to reproduce.  They can't stop it completely or kill it because the virus is already a part of the cell's DNA.  It continues to change and over time can become resistant to the meds and start reproducing again.

Let's see I would say that cancer is curable now, if detected early. The problem is that many people don't go to the doctor for regular check ups.  In the case of AIDS is caused by a virus. The scientific community knows little about viruses, and the HIV virus is constantly mutating, making it difficult to find something that would stop it.  They might find something that works for a certain strain of a virus but soon that strain will mutate, so the it won't work.  I hope that help you a little to understand that even with the resources it is not easy to find cures to things that are constantly changing.

Aids is a disease that is spread through intercourse with different partners during sexual acts, or sharing dirty infected needles for drug useage, or even from bodily fluids being exchanged... \n\nSource(s):\nHIV is transmitted through direct contact of a mucous membrane or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, preseminal fluid or breast milk. This transmission can come in the form of: (anal or vaginal) sex; blood transfusion; contaminated needles; exchange between mother and infant during pregnancy, childbirth, or breastfeeding; or other exposure to one of the above bodily fluids.\n\nhttp://en.wikipedia.org/wiki/aids...

HIV (Human immunodeficiency virus) attacks the body's immune system. When it does, HIV weakens the body's ability to fight off infection. If left untreated, HIV will eventually weaken the immune system so much that the person will become sick from certain types of infections. When the person gets these infections, he or she is said to have AIDS (acquired immunodeficiency syndrome). For some, it takes a long time to develop these infections and therefore AIDS. For others it takes less time. Not everyone with HIV has AIDS and AIDS is not the same as HIV.

It can transmit HIV, the virus that can lead to AIDs.

aids can be contracted through sex and transferring of blood. aids can use semen and.. female sexual fluid (wtf?!) as a medium of travel, and blood. but in the case of blood, it has to enter through your blood stream (like someone has to bleed onto an open wound you have), or i guess if you have blood along with intercourse and stuff. gross

HIV cannot live long outside the human body. It is spread by contact with infected body fluids: semen, vaginal fluids, breastmilk, & blood. It is detectable in the urine and saliva, but hasn't been known to be spread through these two routes.\n\nOnce the virus enters the body it binds to a receptor on a T-lymphocyte. That's a type of white blood cell: part of the immune system. HIV is a retrovirus. It injects it's RNA into the T-cell. An enzyme converts the single strand of RNA into a double DNA strand, similar to the type of DNA you already have but with the virus's info on it. (It's a bit more complicated than that.) \n\nThen the viral DNA joins with the rest of the cell's DNA and doesn't do much until it receives a signal. Then it creates more RNA copies that allow it to use the body's cellular machinery to create viral proteins that will be assembled together into new HIV viruses. The new viruses move to the edge of the cell, bud out of it and move on to infect other cells.\n\nThe T-cells that the HIV virus infects aren't able to preform their usual function of telling the other immune system cells when and what to do because their cellular machinery is too busy making viral proteins. This causes the body to be susceptible to all sorts of other illnesses that it wouldn't usually be susceptible to. These other illnesses are usually what kills AIDS patients.\nThe work to find a cure for HIV/AIDS seems to focus on two areas. The first is preventing the HIV from ever attaching to the T-cells in the first place (preventing transmission). The second is to prevent the HIV from replicating inside cells it has already infection (for current patients). \n\nHope that helps a bit.

First off hiv needs blood.  Just simply touching something doesn't transfer the disease, they has to be broken skin and blood transfer, and then the one receiving has to have broken skin and receive the transfer on that area.  The toothbrush thing I believe was referring to people (eeewwww) that would brush their teeth and then had the brush, right then to their partner or someone else.\nIf you get infected body fluids on your person, in a faily short period of time, last time I heard it lived around 30 second, touched a cut or a orface then ya, you could, maybe get it, but that's alot of if's and maybe's.  If the disease spread that easily, we would all have it by now.  The thing I don't understand is what about mosquitoes?  They have the infected material, in their bodies, and move to the next person?  If I was to worry about something, that would be it.

No.\n\nAs other have said, HIV transmisison requires much more than "touching" a person with "full blown AIDS".  It requires the exchange of infected bodily fluids; blood, semen, vaginal excretions, breast milk, etc.  This isn't the Star Trek episode that depicted an illness that was transmitted though sweat.\n\nAlso, HIV lives for a very short time outside the body--mere seconds at most; not 24 hours.\n\nFinally, if merely touching someone with AIDS could transmit HIV many, many more people would have HIV.  More than likely, we all know someone with HIV or knows someone who knows someone or knows someone who knows someone who knows....  well, you get the idea....

There are currently drugs available that enabled a HIV positive person to live a normal life span. The treatment is not cheap, but for someone living in the US, HIV is not a death sentence anymore. \n\nThere are also studies underway that indicate that certain combination of those drugs prevent the user from getting HIV, similar to Malaria prevention drugs. Those studies look very positive, but a prevention is not a cure. \n\nTo completely eradicate the HIV disease, a vaccine would be required and that still seems to be some time in the future.

aids doesn't kill you but it distroys your immune system so youo can't fight off any diseases.

Acquired immunodeficiency syndrome, or acquired immune deficiency syndrome (or acronym AIDS or Aids), is a collection of symptoms and infections resulting from the specific "damage to the immune system" caused by infection with the human immunodeficiency virus (HIV).\n\nTherefore, it damages the immune system of the affected person thereby making him/her prone to opportunistic infections and tumors.

a person can get affected to AIDS under three circumstances:\n1. through unsafe sex\n2. through (HIV)infected blood transfusion or using the infected needle\n3. through an HIV affected pregnant mother to her unborn child

HIV cannot be cured - even in the early stages.  \n\nI think the poster above is thinking of medications you can give someone who has been stuck with an infected needle.  Those medications are given immediately after exposure.  They prevent HIV from infecting cells.  But, once you're infected with HIV - you always will be.  There is no cure.\n\nHIV attacks something called your "T-cells".  They are part of your immune system.  Their job is to stimulate an immune response in your body.  As HIV progresses, you have less and less T-cells.  It becomes easier to get sick.  \n\nDoctors measure how sick someone is by counting t-cells in a sample of your blood.  \n\nA healthy person has 800 - 1200.  \n\nA person who has HIV, and their T-cell count is 500 or below is diagnosed with HIV-related illness.  This means that it's easier to get sick from common things like bacterial or fungal infections, etc.\nIt also means they might want to make some decisions about medications.\n\nA person is diagnosed with AIDS when their T-cell count is 200 and below.  At this point, people are susceptable to many different infections because their immune system has been damaged by HIV.

There are three reasons listed, at the site provided below, why it is impossible for a mosquito to transfer HIV.\n\nhttp://www.rci.rutgers.edu/~insects/aids.htm\n\nHIV is a virus, and, as we’ve mentioned in other questions and answers, HIV doesn’t do so well outside the human body. Once in the mosquito, the HIV would die very quickly. The mosquito never becomes HIV-infected, and nobody has ever become HIV-infected from a mosquito bite.\n\nhttp://hivinsite.ucsf.edu/insite?page=ask-05-11-09-02\n\nWhen 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. \n\nhttp://www.ode.state.or.us/opportunities/grants/hklb/hiv-aids/hivqandas.aspx

Let's try education. HIV can be transmitted via sex, but also by blood transfusions, blood contact, kissing, needles and other methods of bodily fluid transfer. HIV is not a conviction and does not condem a person for a way of life. Some have been transfered unknowingly by someone else's life style. It is not a judgement. and should not be treated as such.

The problem lies with the culture of the areas.  They don't realize that sex spreads HIV.  In fact its thought that the only way to get rid of the disease is to have sex with a virgin.  Its a sad world we live in indeed.  Also note that they are used to poor hygiene.  This is a leading problem.  I'm not saying everyone over there is like that, but some people is all it takes.    On a side note, the fact that we aren't exposed to the viral epidemics (affects our tolerance and our immune systems ability to cope with the disease) has a small part to play as well.
