HIV/AIDS prevalence

HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system, and if untreated, can lead to AIDS (Acquired Immunodeficiency Syndrome), a condition where the immune system becomes severely weakened. Globally, millions of people live with HIV, with prevalence varying by region. Some areas, like parts of sub-Saharan Africa, have higher infection rates due to factors like limited healthcare access and awareness. HIV spreads mainly through unprotected sex, sharing needles, or from mother to child during birth. Advances in treatment enable many people to manage the virus effectively, reducing the risk of progression to AIDS.
