In early November, WHO initiated a joint WHO/GoB/UNFPA/UNHCR/IOM/UNICE data collection exercise of all health facilities within and near the Rohingya refugee sites, with the aim of mapping facility locations. The first version was published on the 18th November with data collected between the 8th and 12th of November. This second version is an update to the previous version and contains information collected until December 12th, 2017. However, due to the highly dynamic nature of the situation, new health facilities are still being constructed and others removed. It is therefore important to note that this may not be comprehensive or truly representative of infrastructure at the time of publication. Also note that the spatial accuracy of this dataset is at best just under 5m, which can influence the analysis of infrastructure coverage.
