HIV
HIV, or Human Immunodeficiency Virus, is a virus that attacks the immune system, specifically targeting CD4 cells, which are crucial for fighting off infections. If left untreated, HIV can lead to AIDS (Acquired Immunodeficiency Syndrome), a condition where the immune system is severely weakened, making the body vulnerable to opportunistic infections and cancers. Early detection and treatment with antiretroviral therapy (ART) can help people with HIV live long and healthy lives.
