GPH 74: HIV/AIDS

HIV/AIDS has shaped modern public health more profoundly than almost any other infectious disease. Since its emergence in the late twentieth century, it has caused millions of deaths, reshaped global health governance, and driven innovation in prevention, treatment, and human rights advocacy.This episode examines:• Global epidemiology and regional variation• Modes of transmission and key populations• Antiretroviral therapy (ART) and treatment as prevention• Pre-exposure prophylaxis (PrEP) and biomedical prevention• Mother-to-child transmission prevention• Stigma, discrimination, and legal barriers• Health system strengthening through HIV programmes• Funding mechanisms and global partnerships• The goal of epidemic control and eliminationHIV/AIDS illustrates the intersection of biology, behaviour, inequality, and political response. The advent of effective antiretroviral therapy transformed HIV from a fatal diagnosis into a chronic, manageable condition. Yet disparities in access persist, particularly in sub-Saharan Africa and among marginalised populations.The episode highlights how sustained investment, community mobilisation, and evidence-based policy have reduced incidence and mortality in many settings - while emphasising the need for continued vigilance and equity.HIV/AIDS is both a scientific and social story - one of resilience, advocacy, and systemic response.────────────────────────────Key Takeaways• HIV/AIDS remains a significant global health issue• Antiretroviral therapy dramatically reduces mortality and transmission• PrEP and prevention of mother-to-child transmission are highly effective• Stigma and legal barriers impede progress• Global funding partnerships have shaped HIV response• Epidemic control requires sustained investment• Equity remains central to elimination efforts This is a public episode.
