Abstract
It is estimated that almost a half of all of people living in developing countries today are infected with roundworms, hookworms, or whipworms or combinations of these types of intestinal nematode worms.
Author Summary
Almost one in every two people in the developing world is infected with one or more types of intestinal nematode worms. When fewer than 50% of people are infected, most carry only a few worms; but when more than 50% are infected, the number carrying moderate to heavy numbers increases markedly, as does the risk of disease.
Introduction
In 2008 the Copenhagen Consensus ranked five nutritional interventions among the top ten of more than 40 proposals to answer the question: what would be the best ways of advancing human welfare globally? [1] Deworming and other nutrition programmes in school were ranked as the sixth best intervention overall when considering their potential benefit to cost ratio, anticipated feasibility and sustainability [1].
Methods
The cost of giving mass treatment with an anthelmintic drug was estimated in three ways: as the cost per person treated, as the cost per infected person treated, and as the cost per moderately-to-heavily infected person treated.
Results
Table 1 shows the values of p, M and k used to estimate the proportions infected with between 5 or more to 20 or more Ascaris lumbricoides with the cost per person, per infected person and per diseased person, depending on the threshold number of worms used to define disease.
Discussion
The analysis presented here indicates that a prevalence of infection with any species of intestinal nematode worm of 40% or more provides a cost-effective threshold at which to give mass treatment once a year.
Supporting Information
Data for each country on the prevalence of infection with any of the main types of intestinal nematode worm, the population aged 0–15 years and the proportion aged 2–14 y, used for the classification of countries in Table 3 and the calculations in Table 4.
