HIV is a virus that attacks the immune system and can develop into AIDS if untreated. It is most commonly transmitted through unprotected sex or sharing drug needles. While there is no cure for HIV/AIDS, antiretroviral treatment can suppress the virus. Juvenile HIV cases are growing due to lack of knowledge about prevention, risky sexual behaviors, and substance abuse. Biological and structural factors like poverty and lack of access to healthcare also contribute to rising infections among youth. Improving sex education, access to testing and treatment, and addressing social determinants could help curb the fast growth of HIV among teenagers.
