AIDS is caused by the human immunodeficiency virus (HIV). People infected with HIV are open to infections that are harmless in healthy people, but can prove fatal in them as their immune systems are greatly weakened. HIV transmission can come through sex, blood transfusion, childbirth or breastfeeding. There is no cure for AIDS, but new drugs have been invented to help lengthen and improve the quality of life for people with AIDS.
