HIV/AIDS (Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome) - JSS3 Physical and health education Lesson Note

HIV is a virus that attacks the body's immune system, specifically targeting CD4 cells (T cells), which help the immune system fight off infections.

HIV can lead to AIDS, the final stage of HIV infection, where the immune system is severely damaged, making the individual vulnerable to opportunistic infections and cancers.

HIV is primarily transmitted through unprotected sex, sharing needles, and from mother to child during childbirth or breastfeeding.

Symptoms of HIV can vary but may include fever, fatigue, swollen lymph nodes, and a sore throat. Without treatment, HIV can progress to AIDS.

Treatment for HIV involves antiretroviral therapy (ART), which helps suppress the virus, allowing people with HIV to live longer and healthier lives.

Prevention methods include practicing safe sex, using clean needles, getting tested regularly, and taking pre-exposure prophylaxis (PrEP) for high-risk individuals.
