There is no cure forAIDS and no vaccine (疫苗) medicine to prevent it. However, researchers know much more aboutAIDS than they did just a few years ago. We now know thatAIDS 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(遗传的)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.
TheAIDS virus is carried in a person’s body fluids. The virus can be passed sexually or by sharing instruments used to take intravenous (静脉内的) drugs. It also can be passed in blood products or from a pregnant woman withAIDS to her developing baby.

You cannot get it by touching, drinking glasses or other objects used by such persons.Experts say no one has gottenAIDS by living with, caring for or touching anAIDS patient.
