AIDS is the fifth leading cause of death among people aged 25 - 44 in the United States, down from number one in 1995. About 25 million people worldwide have died from this infection since the start of the epidemic, and in 2006, there were approximately 40 million people around the world living with HIV/AIDS.
Human immunodeficiency virus (HIV) causes AIDS. The virus attacks the immune system and leaves the body vulnerable to a variety of life-threatening infections and cancers.
Common bacteria, yeast, parasites, and viruses that ordinarily do not cause serious disease in people with healthy immune systems can cause fatal illnesses in people with AIDS.
HIV has been found in saliva, tears, nervous system tissue and spinal fluid, blood, semen (including pre-seminal fluid, which is the liquid that comes out prior to ejaculation), vaginal fluid, and breast milk. However, only blood, semen, vaginal secretions, and breast milk generally transmit infection to others.
The virus can be transmitted:
Other transmission methods are rare and include accidental needle injury, artificial insemination with infected donated semen, and organ transplantation with infected organs.
HIV infection is not spread by casual contact such as hugging, by touching items previously touched by a person infected with the virus, during participation in sports, or by mosquitoes.
It is NOT transmitted to a person who DONATES blood or organs. Those who donate organs are never in direct contact with those who receive them. Likewise, a person who donates blood is not in contact with the person receiving it. In all these procedures, sterile needles and instruments are used.
However, HIV can be transmitted to a person RECEIVING blood or organs from an infected donor. To reduce this risk, blood banks and organ donor programs screen donors, blood, and tissues thoroughly.
People at highest risk for getting HIV include:
AIDS begins with HIV infection. People infected with HIV may have no symptoms for 10 years or longer, but they can still transmit the infection to others during this symptom-free period. Meanwhile, if the infection is not detected and treated, the immune system gradually weakens, and AIDS develops.
Acute HIV infection progresses over time (usually a few weeks to months) to asymptomatic HIV infection (no symptoms) and then to early symptomatic HIV infection. Later, it progresses to AIDS (advanced HIV infection with CD4 T-cell count below 200 cells/mm3 ).
Almost all people infected with HIV, if not treated, will develop AIDS. There is a small group of patients who develop AIDS very slowly, or never at all. These patients are called nonprogressors, and many seem to have a genetic difference that prevents the virus from damaging their immune system.

STDs, which is an acronym for Sexually Transmitted Disease. They are diseases transferred through sexual activity that ca be extremely painful. They are also far too common in many third world countries.

There are no vaccinations for HIV or AIDS.
anybody can get HIV and then move on to aids.
Correct...HIV can lead to AIDS and AIDS can only be caused be the HIV virus.
HIV is an early form of aids. Every one who has AIDS had HIV at one point.
HIV is the virus that causes AIDS. Hence, HIV in the virus and AIDS is the disease that results from the virus.
HIV is a virus; AIDS is a disease.
HIV is a virus. AIDS is a diagnosis. HIV is contagious and causes a person to develop AIDS. AIDS is not contagious and only occurs in people who are HIV+.
aids is an hiv: human immunodeficiency virus. and hiv is an std.
Yes you can do research on HIV/AIDS.
As HIV infection progresses, it turns into AIDS.
