What Is AID and HIV.
AIDS is one of the most serious, deadly diseases in human history.
More than 20 years ago, doctors in the United States identified the first cases of AIDS in San Francisco andNew York. Now there are an estimated 42 million people living with HIV or AIDS worldwide, and more than 3 million die every year from AIDS-related illnesses.

But as HIV destroys these lymphocytes, people with the virus begin to get serious infections that they normally wouldn't — that is, they become immune deficient. Thename for this condition is acquired immunodeficiency syndrome(AIDS).
As the medical community learns more about how HIV works, they've been able to develop drugs to inhibit it (meaning they interferewith its growth). These drugs have been successful in slowing the progress of the disease, and people with the disease now live much longer. But there is still no cure for HIV and AIDS.
Hundreds ofU.S. teens become infected with HIV each year. HIV can be transmitted from an infected person to another person through blood, semen (also known as "cum," the fluid released from the penis when a maleejaculates), vaginal fluids, and breast milk.
