Analysis of community-level factors contributing to cholera infection and water testing access in the Northern Corridor of Haiti.

Vibrio cholera, the bacteria that cause cholera, is endemic in Haiti with a presence in both cities and remote areas. Improved access to drinking water testing and treatment in remote areas may reduce the impact of the disease. This case study uses correlation and regression analysis to identify the main factors that hinder access to water testing and that lead to high cholera infection rates among communities in the Northern Corridor of Haiti. Poor road conditions, mountainous terrain, and limited transportation options lead to high travel times up to 5.7 min/km between remote communities and drinking water testing facilities. The presence of springs in a community has a significant positive correlation with cholera infection rates in the Northern Corridor. However, socioeconomic factors had no significant correlation with cholera infection rate. The results of this study will be used to plan the implementation of a new drinking water testing laboratory near the city of Cap-Haitian and other programs for vulnerable remote areas. PRACTITIONER POINTS: Topography and road conditions may be more important than distance in determining the accessibility of water testing facilities for rural communities. A lack of access to private vehicles is a substantial challenge for many rural communities in accessing water testing. The presence of springs in a community had a significant positive correlation with cholera infection rate.
