In this report, we present a Gender-Based Analysis (GBA) of HIV/AIDS in Belize. Added analysis of sexually transmitted infections (STIs) and gender-based violence (GBV) is provided, as they affect biological risks and social vulnerabilities and help inform the GBA of HIV/AIDS. The objective is to explore current epidemiological patterns and trends, access to testing and treatment, health-related outcomes, and various risk factors associated with contracting HIV/AIDS among men, women, boys and girls living in Belize.
