HIV/AIDS-causes and prevention



Human Immunodeficiency Virus is a virus that attacks the immune system. HIV infects and destroys certain white blood cells called CD4+ cells. The last stage of HIV infection is AIDS (Acquired Immunodeficiency Syndrome).
HIV is transmitted primarily through unprotected sexual intercourse (including anal and oral sex), contaminated blood transfusion, hypodermic needles and from mother to child during pregnancy, delivery or breastfeeding.
Common methods of HIV/AIDS prevention include, encouraging and practicing safe sex, avoiding any behavior that allows HIV-infected fluids into your body, making you use sterile needles and not sharing sharp objects.
There is no vaccine to prevent HIV infection and no cure for AIDS.  It is better to get tested and know your status because the sooner a person is diagnosed, the better the chances of staying healthy and living a normal lifespan
