The World Health Organization says as many as 10 million persons worldwide may have the virus that causes AIDS. Experts believe about 350 thousand persons have the disease. And one million more may get it in the next five years. In the United States, about 50,000 persons have died with AIDS. The county’s top medical official says more than 90 percent of all Americans who had the AIDS virus five years ago are dead. There is also no cure for AIDS and no vaccine medicine to prevent it. However, researchers know much more about AIDS than they did just a few years ago. We now know that AIDS is caused by a virus. The virus invades healthy cells including white blood cells that are part of our defense system against disease. It takes control of the healthy cell’s genetic material and forces the cell to make a copy of the virus. The cell then dies. And the viral particles move on to invade and kill more healthy cells. The virus is carried in a person’s body fluids. The virus can be passed sexually or by sharing instruments used to take intravenous drugs. It also can be passed in blood products or from a pregnant woman with AIDS to her developing baby. Many stories about the spread of AIDS are false. You cannot get AIDS by working or attending school with someone who has the disease. You can not get it by touching, drinking glasses or other objects used by such persons. Experts say no one has gotten AIDS by living with, caring for or touching an AIDS patient. There are several warning signs of an AIDS infection. They include always feeling tired, unexplained weight loss and uncontrolled expulsion of body wastes. Other warnings are the appearance of white areas on the mouth, dark red areas of skin that do not disappear and a higher than normal body temperature. 26.
