The World Health Organization (WHO) recommends preventive chemotherapy (PC) as the primary intervention to control morbidity of soil-transmitted helminthiasis (STH). In this series of maps, we present the total quantity of anthelminthic drugs donated (albendazole + mebendazole) for PC intervention in the different countries (different shades of green). The graphs attached to each country map show the available data between 2019 and 2023. The quantity of albendazole is referred to the albendazole distributed for STH control plus the 25% of the total quantity of Albendazole distributed for Lymphatic Filariasis (LF) elimination (25% is the rate approximately distributed for the treatment of LF in school-age children). Any suggestion and update from WHO's regional and country offices and Ministries of Health are more than welcome to improve the website.

The boundaries and names shown and the designations used on this map do not imply the expression of any opinion whatsoever on the part of the World Health Organization concerning the legal status of any country, territory, city or area or of its authorities, or concerning the delimitation of its frontiers or boundaries. Dotted and dashed lines on maps represent approximate border lines for which there may not yet be full agreement. The borders of the map provided reflect the current political geographic status as of the date of publication (2021). However, the technical health information is based on data accurate with respect to the year indicated (2020). The disconnect in this arrangement should be noted but no implications regarding political or terminological status should be drawn from this arrangement as it is purely a function of technical and graphical limitations.
