This document summarizes Haiti's cholera situation as of November 16, 2016. Between January and October 2016, Haiti reported 35,203 new suspected cholera cases (32% increase from 2015) and 369 deaths (56% increase). After Hurricane Matthew, cases rose dramatically, with 52% of new cases concentrated

in Grand'Anse and South departments. Since the 2010 outbreak began, Haiti had experienced 797,000 total cases and 9,353 deaths. The report identifies key factors contributing to cholera persistence: weak water and sanitation infrastructure, limited healthcare access, underfunding, population density, and mobility. Despite concerning trends, humanitarian partners were cautiously optimistic as a feared nationwide outbreak following Hurricane Matthew had not materialized, and a vaccination campaign was underway. However, the cholera response was significantly underfunded, with only 42% of requested funds received.

On 19 August 2016, the former UN Secretary-General announced a new approach to cholera in Haiti, consisting of two tracks. Track 1 focuses on reducing cholera transmission, improving access to care, and addressing water, sanitation, and health system issues. Track 2 aims to provide material assistan

ce to those most affected by cholera. The Secretary-General urged Member States to show solidarity with Haiti by increasing contributions. The UN General Assembly, in resolution 71/161, recognized the UN's moral responsibility to cholera victims and called for support to eliminate cholera and address its victims' suffering. The Secretary-General was requested to provide an update on the progress of this approach.

This article describes WHO's efforts to combat a cholera outbreak in South Sudan in July 2017. The organization received 500,000 doses of oral cholera vaccine (OCV) and was working with South Sudan's Ministry of Health to launch a vaccination campaign from July 28 to August 3, 2017. At the time, the

country had reported 17,785 cholera cases and 320 deaths since the outbreak began in June 2016. The vaccination campaign targeted four counties with high transmission rates: Tonj East, Kapoeta South, Kapoeta North, and Kapoeta East. South Sudan was implementing an integrated approach to control cholera, combining patient care, surveillance, social mobilization, water and sanitation improvements, and vaccination. The article notes that approximately 6 million people in South Sudan were facing starvation, with food insecurity and drought exacerbating the risk of cholera spread as people resorted to using contaminated water sources.

Il identifie trois types de zones : zones sources (A), zones épidémiques (B) et zones de diffusion (C), chacune nécessitant des interventions adaptées. Les stratégies incluent l’amélioration des infrastructures d’eau potable et d’assainissement, la surveillance épidémiologique, la prévention, la prise en charge médicale et la coordination des actions.
Malgré des progrès dans certaines régions, la mise en œuvre du plan a rencontré des défis, notamment en raison du manque de financements et de la persistance de foyers endémiques dans l'Est du pays. Une coordination nationale et internationale est essentielle pour mobiliser les ressources et atteindre l'objectif d'élimination du choléra en RDC.
