　　Throughout the world 36 million people are suffering from AIDS，which is more than the whole population of Australia. At present，AIDS is the fourth leading cause of death in the whole world，and the chief culprit in Africa. In Africa，it deprives jobs of the workers，families of incomings and children of their parents. In seven African countries，more than 20 percent of the 15-to-49-year-old population is infected with HIV.
