Epidemiologic Models, Key Logs, and Realizing the Promise of WHA 54.19

Highlights

During the late 1800s, when trees were cut by handsaw and the logs floated down river by the hundreds to be milled, they occasionally jammed
The primary goal was not interruption of transmission, which, in the absence of adequate water, sanitation, and hygiene education (WASH), is unrealistic, but rather, reduction in soil-transmitted helminthiasis (STH) morbidity associated with high worm burdens
World Health Organization (WHO) has prioritized scaling up treatment for the estimated 615 million school-age children at risk of STH morbidity [6,7,8]

Summary

Introduction

During the late 1800s, when trees were cut by handsaw and the logs floated down river by the hundreds to be milled, they occasionally jammed. In 2001, a World Health Assembly resolution (WHA 54.19) called for regular administration of preventive chemotherapy to at least 75% of school-age children at risk of STH morbidity. WHO has prioritized scaling up treatment for the estimated 615 million school-age children at risk of STH morbidity [6,7,8].
