Guideline: preventive chemotherapy to control soil-transmitted helminth infections in at-risk population groups; 2017

This guideline on Preventive chemotherapy to control soil-transmitted helminth infections in at-risk population groups updates and supersedes previous recommendations contained in the World Health Organization (WHO) publication Preventive chemotherapy in human helminthiasis: coordinated use of anthelminthic drugs in control interventions: a manual for health professionals and programme managers, which was reviewed at the Informal Consultation on Preventive Chemotherapy in Human Helminthiasis (Geneva, March 2006), and complements some of the operational guidance of Helminth control in school-age children: a guide for managers of control programmes, published by WHO in 2011.

In order to produce this guideline, the rigorous procedures described in the WHO handbook for guideline development were followed. This document presents the evidence that served to inform the recommendations contained herein, and provides expanded sections on dissemination as well as on ethical and equity considerations, summarized in the most recent reviews on these topics.
