Since the notification of the first two confirmed cases of Vibrio cholerae O1 in the greater Port-au-Prince area on 2 October 2022, to 7 January 2022, the Haitian Ministry of Health (Ministère de la Santé Publique et de la Population, MSPP per its French acronym)2, reported a total of 23,044 suspected cases (Figure 1) in 10 departments of the country, including 1,576 confirmed cases, 18,699 hospitalized suspected cases, and 464 registered deaths3.

The current conditions in Haiti must be considered when analyzing the epidemiological situation of this cholera outbreak using the available official data. Epidemiological surveillance is affected due to the complex humanitarian and security crisis, added to the limited access to fuel throughout the country, resulting in limited access to health services and laboratories. Moreover, most of the population in the country is in a highly vulnerable situation in the face of established cholera transmission chains in the departments and municipalities. The humanitarian crisis and insecurity have exacerbated in recent months. This has considerably undermined the efforts of the MSPP and other organizations to implement prevention and control measures, including epidemiological surveillance, leading to underreporting of cases.
The Pan American Health Organization / World Health Organization (PAHO / WHO) is working in coordination with the Haitian public health authorities to characterize this event and support the response.
