Hiv - GCSE Biology Definition

Reviewed by: Lára Marie McIvor

Published

HIV stands for Human Immunodeficiency Virus, which is a virus that attacks the body's immune system, specifically the white blood cells known as T-helper cells or CD4 cells. Over time, HIV can weaken a person's immune system so much that they become more vulnerable to infections and diseases, a condition known as AIDS (Acquired Immunodeficiency Syndrome). HIV is primarily spread through certain body fluids, such as blood, semen, vaginal fluids, and breast milk, often through unprotected sex, sharing needles, or from mother to child during childbirth or breastfeeding. While there is currently no cure for HIV, there are treatments available that can help manage the virus and allow individuals to live long, healthy lives.
