Up to 1.2 billion people – about 20 percent of the world’s population – are infected or at risk
Children are estimated to represent about one-third (400 million) of the global STH burden.
The highest rates of infection are often in children between ages five and 15.
In high-transmission areas, regular treatment will stop the infection from developing into serious disease.
Fewer than 20 percent of the at risk school-age children were reached with deworming treatment in 2005 – far short of the World Health Assembly’s target to regularly treat 75 percent of at risk children by 2010.
Transmission of STH can be controlled through regular treatment with mebendazole, hygiene education, and provision of water and sanitation facilities.
