Attempts to estimate the cost-effectiveness of deworming within the disability-adjusted life-year (DALY) framework have been problematic.We provide a deeper overview of the evidence for long-term effects of deworming below and at two blog posts: here and here. We find these studies to constitute evidence that is suggestive, though not conclusive or necessarily representative (the intensity of worm infections in this study was substantially heavier than the intensity of worm infections in most contexts where deworming is carried out today).

A series of follow-ups to one experiment ( Miguel and Kremer 2004) finds that reducing worm infection loads during childhood can have a significant later impact on income.

We would guess that deworming has small impacts on weight, but the evidence for its impact on other health outcomes is weak.

Evidence for the impact of deworming on short-term general health is thin.

There is strong evidence that administration of the drugs reduces worm loads, but weaker evidence on the causal relationship between reducing worm loads and improved life outcomes.

The benefits are potentially major, but also debatable: parasitic infections rarely cause mortality or other acute effects, and the evidence on their impact on quality of life is thin. Mass deworming is generally very inexpensive on a per-person-treated basis (in the range of $0.50). Also, side effects of the drugs are believed to be minor thus, everyone in a given population (sometimes schoolchildren sometimes the community at large) is treated, without being individually tested for the presence of infections.

Treatment is cheaper than diagnosis and usually takes place in areas where worms are fairly common. Mass deworming involves treating large numbers of people with parasite-killing drugs: praziquantel kills the parasites that cause schistosomiasis, while albendazole kills soil-transmitted helminths. We focus our discussion on work similar to that of deworming programs implemented by several of our top charities. This page discusses the general case for mass deworming.
