Human Immunodeficiency Virus (HIV)

HIV infection is caused by a virus that attacks the immune system and destroys cells that fight off other infections and diseases. AIDS is the most severe phase of HIV infection. HIV is most commonly spread through unprotected sex and sharing HIV-contaminated needles or syringes. There is no cure for HIV/AIDS, but it can be effectively managed through treatment.
