The greatest burden of trachoma is found in sub-Saharan Africa (SSA), particularly in countries along the Sahel belt and in East Africa. In the last decade, sixteen countries have conducted surveys providing clinical data on a national level or covering large endemic regions. However, many countries still have insufficient data to generate reliable estimates of disease burden and inform control strategies to reach the 2020 elimination targets.
The developed maps collate available information into a single database and present the known distribution of infection. These regions have the most immediate need for reliable, up-to-date distribution maps to demonstrate the current burden of disease and encourage further support from the NTD community.
