Human Immunodeficiency Virus (HIV) is a virus that causes Acquired Immune Deficiency Syndrome (AIDS) if left untreated. HIV can be transmitted through unprotected sex, sharing needles, from mother to child during birth or breastfeeding, or exposure to infected blood. Common modes of transmission within the Hispanic population include substance abuse and men who have sex with men. Factors influencing HIV infection rates among Hispanics include mental health issues like depression, abuse, risky sexual behaviors, and obstacles to prevention such as stigma, language barriers, and poverty.
