JunHa Kim ESOL 103B Final Draft Cause and Effect Essay Effects of AIDS and HIV When I was a high school student, I watched a movie in my biology class. The name of the movie was “Osmosis Jones”, and the movie was about medicine and white blood cells, fighting with a virus and driving it away from person’s body. After watching, I thought that if white cells don’t work, it would be possible for a human to die even from a little illness such as a cold. I didn’t know at that time, but this thought was not imaginary. It happens through the disease called AIDS. AIDS (Acquired Immunodeficiency Syndrome) is a condition in which the body’s immune system breaks down and is unable to fight off infection. AIDS is caused by a virus called HIV, the Human Immunodeficiency Virus. The HIV virus weakens the immune system, leaving the body vulnerable to infection (“Coping with AIDS and HIV ) AIDS, for which there is no certain cure, seriously affects all aspects of a person’s life. The effect of AIDS can be divided into three problems: physical problems, mental problems and emotional problems. The number of people with AIDS or HIV is increasing steadily every year. There are at least 38.6million people living with HIV in the world.

The virus can enter the body through the mucosal linings of the vagina, vulva, penis, or rectum after intercourse or, rarely, via the mouth and possibly the upper gastrointestinal tract after oral sex. HIV also can be transmitted by contact with infected blood, most often by the sharing of needles or syringes contaminated with minute quantities of blood containing the virus. The virus also may be transmitted from an HIV-infected mother to her infant during pregnancy, delivery, or breastfeeding. (“Cause of HIV/ AIDS ) The most critical physical problem of AIDS is people are eventually killed. According to statistic in “HIV Statistics - Estimates of the World's HIV Epidemic” the number of AIDS deaths in 2006 is 2.9 million. After a person is exposed to HIV, HIV attaches to the body's infection fighting cells (called CD4 or T cells) in the immune system. The virus infects CD4 cells and copies its own genetic code into the cell's DNA. The CD4 cell is then "programmed" to create new copies of HIV. The new viruses are released from infected CD4 cells into the blood and go on to infect and destroy other CD4 cells. As CD4 cells are attacked and destroyed by HIV, the immune system becomes less able to fight infection and
