Here’s a look at the disease’s origins, treatment, and global response HIV and AIDS.

HIV stands for Human Immunodeficiency Virus.

AIDS Stands for Acquired Immunodeficiency Syndrome.

HIV AIDS Spread through sexual contact with an infected person, sharing needles with an infected person, transfusion of infected blood, or through an infected mother.

People living with HIV experience three phases Infect:

  1. Acute infection, or acute retroviral syndrome, can produce flu-like symptoms in the first month after infection.
  2. Clinical latency, or asymptomatic HIV infection, in which HIV reproduces at low levels.
  3. AIDS, in which the number of CD4 cells falls below 200 cells per cubic millimeter of blood (as opposed to the normal level of 500-1,500).

Both HIV-1 and HIV-2 can cause AIDS. HIV-1 is the most common human immunodeficiency virus; HIV-2 is mainly found in West Africa.

Antiretroviral therapy (ART) involves taking a mixture of HIV medicines to treat the virus. In 1987, azidethymidine (AZT) became the first drug approved by the FDA for the treatment of HIV/AIDS.
