Contributions of non-governmental organizations to WHO targets for control of soil-transmitted helminthiases

Abstract

Soil-transmitted helminthiases (STH) may affect up to 1 billion children globally. The World Health Organization (WHO) recommends regular preventive chemotherapy for at-risk individuals. The WHO Preventive Chemotherapy (PCT) Databank tracks annual treatments reported by national Ministries of Health (MOHs) to evaluate progress to coverage goals. Non-governmental organizations (NGOs) deliver STH treatments; the extent to which they are included in MOH reports to the WHO is unclear. The Global NGO Deworming Inventory solicited treatment reports from NGOs to compare with the PCT Databank. In 2010, NGOs delivered 65.4 million STH treatments, which is an estimated 25.1% of the total delivered. Of these treatments, 23.3 million (35.6%) were not reported to the WHO; 22.3 million (95.7%) were from countries that had not submitted STH treatment reports to the WHO. Reporting from NGOs to MOHs and from MOHs to the WHO should be strengthened to ensure that progress to WHO treatment goals is monitored with better completeness and assessed accurately.
