There is no cure for AIDS and no vaccine(疫苗) 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(遗传的) material and forces the cell to make a copy of the virus. The cell thendies.And the viral particles move on to invade and kill more healthy cells.The AIDS 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 with AIDS to her developing baby.?
