Table adapted from information in the WHO update on the global status of implementation of preventive chemotherapy (PC) [27].
¹Number of endemic countries moved to post-treatment surveillance stage is not included in total.
²Number of countries reporting data on PC implementation. Countries submitting blank reports are not included in total.
³Proportion of known endemic districts implementing PC for SAC in countries that reported on PC interventions.
⁴Proportion of districts implementing PC achieving the defined effective coverage of SAC population for the disease - > 65% for LF and Onchocerciasis; > 75% for schistosomiasis and STH; > 80% for trachoma.
⁵Coverage is calculated as the number of people in need of PC and treated out of total population requiring PC.
⁶SAC – school-aged children.
