Humanitarian Situation in Haiti. Bulletin 2 Health Cluster. April - June 2026

During the second quarter of 2026, ten major incidents involving armed violence led to the displacement of 50,867 people, a 19% increase compared to the previous quarter. After several months of severe deterioration in the Artibonite and Centre departments, the West department once again became the epicenter of new displacements, accounting for 64% of all movements recorded during the period—primarily due to armed violence in the commune of Cité Soleil. 

A decline in suspected diphtheria cases has been observed starting from the 21st epidemiological week. A total of 42 suspected cases have been reported across 15 sites for internally displaced persons (IDPs) in the West Department (Cité Soleil, Delmas, Pétion-Ville, Port-au-Prince) since January 2026. 

The cholera outbreak has been steadily declining since its resurgence in October 2022. Following a peak of 3,683 suspected weekly cases in 2023, transmission dropped by nearly 80% in 2024. This downward trend continued into 2025 (with 85 cumulative cases recorded during the same period) and into 2026, with 44 suspected cases reported as of July 18 (a 48% decrease). Transmission levels currently remain low and stable, reflecting successful control efforts. Maintaining surveillance and response capabilities remains crucial to preventing a resurgence, given the active circulation of Vibrio and the persistence of risk factors for transmission.
