Water-borne Diseases

Haiti is facing a cholera resurgence with 2,852 suspected cases, 186 confirmed cases, and 48 deaths recorded between January 1 and October 30, 2025, primarily affecting children under 9 (over a third of cases). The outbreak, linked to the rainy season, is spreading in and around Port-au-Prince, exacerbated by collapsing water and sanitation infrastructure, gang violence displacing over 1.4 million people into overcrowded settlements without clean water, and restricted humanitarian access. This marks a continuation of cholera struggles since the 2010 UN-linked epidemic that killed nearly 10,000, following a three-year absence until 2022. Over 225,000 deportations to Haiti from neighboring countries in 2025 heighten risks in vulnerable communities. While cases declined after an 11-week pause, renewed spread alarms health experts amid worsening insecurity and health system collapse. The crisis compounds Haiti's humanitarian emergency, with threats in displacement camps and high-risk zones like Port-au-Prince metropolitan area and Pétion-Ville. PAHO/WHO supports surveillance, treatment centers, and prevention in 66 IDP sites, but gang control limits aid.
