All you need to know about HIV

With the high prevalence of HIV and other STDs, measures like protected sex, monogamy and occasional screening are paramount in keeping such conditions at bay. While the global fight against AIDS (acquired immune deficiency syndrome) has been able to reduce the prevalence of the infection to some extent, a lot remains to be done. AIDS is caused by the human immunodeficiency virus (HIV), which impairs the immune system, adversely affecting the body's ability to fight off infections. When body fluids such as pre-seminal, seminal, vaginal and rectal fluids are exchanged between two people during vaginal, oral or anal sex, they can contract HIV. HIV is a virus that affects the immune system, so it can easily go undetected until you get tested for it. Watch the video to know all about HIV and AIDS.
