HIV/AIDS is a global pandemic caused by the Human Immunodeficiency Virus (HIV). HIV is a virus that attacks the immune system, making it difficult for the body to fight off infections and diseases. It can be transmitted through unprotected sexual contact, blood transfusion, and the sharing of contaminated needles. There is currently no cure for HIV/AIDS, but there are treatments available that can help people with the virus manage their symptoms and live longer, healthier lives. It is important to practice safe sex and get tested regularly to help prevent the spread of HIV/AIDS.
