If you're not quite sure what's up with AIDS these days, don't feel alone. Misconceptions and falsehoods concerning AIDS and HIV abound.
|
|
A person with HIV can look and feel perfectly healthy. But that person can give HIV to others as soon as he or she is infected with the virus.
|
|
New drug treatments can delay the effects of AIDS and are helping patients live longer. But the reality is that no medicine can cure AIDS or the virus that causes it, HIV. Once inside the body, HIV destroys immune system cells, making it difficult to fight off illness.
|
|
What's true and what's not when it comes to AIDS? Here's a look at some common myths surrounding HIV infection and AIDS.
|
|
Acquired immunodeficiency syndrome, or AIDS, is the final, life-threatening stage of infection with any of the human immunodeficiency viruses (HIV-1, its many subtypes, or HIV-2), which are transmitted from person to person sexually (including via anal, oral, and vaginal intercourse, both heterosexually and homosexually), through contact with blood (mainly via equipment used to inject illicit drugs and, rarely, via medical uses of blood), and perinatally (from mother to fetus or newborn during pregnancy, labor, and delivery, or after birth through breast-feeding). ORIGIN AND HISTORY HIV-1 and HIV-2 both appear to have been transmitted to humans from primates in Central and West Africa, probably to hunters or processors of carcasses of primates consumed as food (referred to as " bush meat " ).
|
|
Human immunodeficiency virus (HIV) is a retrovirus that causes acquired immune deficiency syndrome (AIDS) by infecting helper T cells of the immune system. The most common serotype, HIV-1, is distributed worldwide, while HIV-2 is primarily confined to West Africa.
|
 |
HIV (human immunodeficiency virus) was identified in 1983 by the French scientist Luc Montagier and his staff at the Pasteur Institute in Paris. Ever since that discovery, scientists have been searching for ways to treat those infected with HIV, and to produce a vaccine to prevent its spread.
