Define HIV and AIDS:
HIV is the human immunodeficiency virus,and AIDS is the acquired immune deficiency syndrome that is caused by HIV.
List and describe the symptoms:
Most people who become infected with HIV at first experience no symptoms at all. If symptoms do occur, they may resemble those of the common cold or flu, including fever, headache, fatigue, and rashâ€"all the usual signs that the immune system is responding to a foreign microorganism. These signs of infection typically occur within a few days to several weeks after exposure, and usually resolve within one to three weeks; however, these symptoms are too general to serve as reliable indicators of HIV infection.
Over time, HIV microbes continue to multiply in the body, attacking and killing immune system cells, especially CD4+ T-cells, the body's first line of defense against most infections. As the immune system weakens, new and more severe symptoms begin to appear. These include loss of energy; unexplained weight loss; frequent fevers and night sweats; frequent yeast infections; enlarged lymph glands; persistent skin rashes or flaky skin; short-term memory loss; mouth, genital, or anal sores; and blurred vision.
Explain the three types of therapies used to treat HIV:
Treatment consists of a three-pronged approach: attacking the virus itself, strengthening the immune system, and preventing and controlling opportunistic infections and diseases.
