Abstract
Background
Global deworming programs aim to reach 75% of at-risk preschool-age children (pre-SAC) by 2020. The 2013 global pre-SAC deworming coverage initially published by the World Health Organization (WHO) was 23.9%, but this estimate inadequately captured deworming delivered through Child Health Day (CHD) platforms.
Objective
To update global and regional coverage estimates of pre-SAC deworming in 2013 by supplementing data from the WHO Preventive Chemotherapy and Transmission Control (PCT) databank with national CHD data.
Methods
UNICEF country offices (n = 82) were mailed a questionnaire in July 2014 to report on official national biannual CHD deworming coverage as part of the global vitamin A supplementation coverage reporting mechanism. Coverage data obtained were validated and considered for inclusion in the PCT databank in a collaboration between UNICEF and WHO. Descriptive statistical analyses were conducted to update the number of pre-SAC reached and the number of treatments delivered.
Results
Of the 47 countries that responded to the UNICEF pre-SAC deworming questionnaire, 73 data points from 39 countries were considered for inclusion into the WHO PCT databank. Of these, 21 new data points were from 12 countries were newly integrated into the WHO database. With this integration, deworming coverage among pre-SAC increased to 49.1%, representing an increase in the number of children reached and treatments administered from 63.7 million to 130.7 million and 94.7 million to 234.8 million, respectively. The updated databank comprised 98 mass deworming activities conducted in 55 countries, in which 80.4% of the global pre-SAC population requiring deworming reside. In all, 57 countries requiring deworming were not yet represented in the database.
Conclusions
With the inclusion of CHD data, global deworming programs are on track to achieving global pre-SAC coverage targets. However, further efforts are needed to improve pre-SAC coverage reporting as well as to sustain and expand deworming delivery through CHDs and other platforms.
Soil-transmitted helminthiases are a group of parasitic diseases caused by intestinal worms that are linked to poor physical and cognitive development among preschool aged children. The administration of deworming drugs designed to reduce the intensity of the worm infection in the child is effective and efficient intervention to control the disease and has set the goal of deworming 75% of at-risk children by 2020. However, global WHO-reported coverage decreased from 37.1% to 24.7% from 2010 to 2012. In 2013, the first coverage estimate released was 23.9%, but as in previous years, this estimate did not adequately capture coverage achieved through Child Health Days, which are integrated campaign-style events where deworming is often co-delivered alongside vitamin A supplementation and other high impact child interventions. In this paper, we mailed a questionnaire to UNICEF country offices requesting data pertaining to preschool age deworming conducted through Child Health Days. After reviewing submissions and integrating data into the global databank, we report that the global coverage now stands at 49.4% putting us on track to achieve the global goal by 2020. The sharp increase in coverage illustrates the importance of Child Health Days for attaining global pre-SAC coverage goals.
