AIDS (Acquired Immunodeficiency Syndrome) is the most advanced form of HIV infection. While HIV is the virus that assaults the immune system, AIDS is the disease in which the immune system is severely weakened, leaving the body vulnerable to opportunistic infections and certain malignancies. Not everyone with HIV will get AIDS, especially if they receive adequate care.
HIV is spread by the exchange of bodily fluids such as blood, semen, vaginal fluids, rectal fluids, and breast milk. Common means of infection include unprotected sexual contact, sharing needles or syringes, mother-to-child transmission during childbirth or breastfeeding, and, in rare situations, contaminated blood transfusions or organ transplants.
HIV cannot be transferred by casual contact, such as hugging, shaking hands, sharing utensils, using the same toilet, or exchanging saliva, sweat, or tears. The virus can only be spread by direct contact with particular bodily fluids.
AIDS prevention focuses mostly on preventing HIV transmission. Key strategies include practicing safe sex (using condoms), frequent HIV testing, taking Pre-Exposure Prophylaxis (PrEP) if at high risk, avoiding needle sharing, and ensuring that HIV-positive pregnant women receive effective treatment to prevent mother-to-child transmission.
PrEP (pre-exposure prophylaxis) is a daily medicine that lowers the chance of developing HIV. It is indicated for those who are at high risk of HIV infection, such as those with an HIV-positive partner, those who have several sexual partners, or those who use injectable drugs.
