The global progress of soil-transmitted helminthiases control in 2020 and World Health Organization targets for 2030

It is shown that STH-attributable morbidity can be averted with evidence-informed program planning, implementation, and monitoring, and caution will still need to be exercised in stopping control programs to avoid any rebound of prevalence and loss of accrued morbidity gains.

A systematic analysis for the GBD study found that a high percentage of anemia disease burden in Oceania and Africa could be attributed to hookworm infection.

Perspective: Opportunities and Scope for Expanded Deworming Programs for Soil-Transmitted Helminths in India

Understanding gaps in deworming will help plan policy changes and program strategies for STH elimination in India, which has 21% of the global STH burden, as well as in other STH endemic countries.

Impact of Annual Albendazole versus Four-Monthly Test-and-Treat Approach of Intestinal Parasites on Children Growth—A Longitudinal Four-Arm Randomized Parallel Trial during Two Years of a Community Follow-Up in Bengo, Angola

This study did not show that a 4TT intestinal parasites approach results on better growth outcomes of children when compared with annual ALB, with exception of height and WHZ using GEE model at 5% level.

Health, financial, and education gains of investing in preventive chemotherapy for schistosomiasis, soil-transmitted helminthiases, and lymphatic filariasis in Madagascar: A modeling study

This analysis incorporates financial and education gains into the economic evaluation of health interventions, and therefore provides information about the efficiency of attainment of three Sustainable Development Goals (SDGs).

Prevalence of intestinal parasitic infections in Brazil: a systematic review

The prevalence of intestinal parasitic infections is high in Brazil, and anthelmintic drugs should be administered periodically as a prophylactic measure, as recommended by the World Health Organization.

Prevalence and determinants of undernutrition among children of local farmers in central Malawi

It is suggested that programs that can promote access to potable water, food security, child deworming, improving child birth weight, and reduction of IPV against mothers can reduce the risk of child undernutrition.

Extending the global worm index and its links to human development and child education

Treating intestinal worm infections leads to improved human development and childhood education, shows a study in PLOS Neglected Tropical Diseases.



Commentary: Replication of influential trial helps international policy

There is a correlation between the number of observations in each school and the reported attendance, with more observations associated with lower attendance reported—except in some of the intervention groups, where more frequent observation is associated with better attendance, which raises the possibility that the process of observation influenced outcome reporting and this was different in control and intervention groups.

When Should Governments Subsidize Health? The Case of Mass Deworming

We discuss how evidence and theory can be combined to provide insight on the appropriate subsidy level for health products, focusing on the specific case of deworming. Although intestinal worm

Disease and Development: Evidence from Hookworm Eradication in the American South.

Evidence is found that eradication increased the return to schooling and areas with higher levels of hookworm infection prior to the RSC experienced greater increases in school enrollment, attendance, and literacy after the intervention.

Does Mass Deworming Affect Child Nutrition? Meta-Analysis, Cost-Effectiveness, and Statistical Power

The TMSDG analysis is underpowered: Power is inadequate to rule out weight gain effects that would make MDA cost effective relative to comparable interventions in similar populations, and underpowered to reject the hypothesis that the effect of MDA is different from the effect that might expected, given deworming's effects on those known to be infected.

Worms at Work: Long-run Impacts of a Child Health Investment*

The program increased labor supply among men and education among women, with accompanying shifts in labor market specialization, and it is shown that mass deworming may generate more in future government revenue than it costs in subsidies.

I investigate whether a school-based deworming intervention in Kenya had long-term effects on young children. I exploit positive externalities from the program to estimate impacts on younger children

Deworming drugs for soil‐transmitted intestinal worms in children: effects on nutritional indicators, haemoglobin, and school performance

The effects of giving deworming drugs to children to treat soil‐transmitted helminths on weight, haemoglobin, and cognition; and the evidence of impact on physical well‐being, school attendance, school performance, and mortality are summarized.
