Drenching Merino hoggets, Walcha, NSW U.S. soldiers treating animals with de-worming medication in Eswatini during VETCAP. Deworming (sometimes known as worming, drenching or dehelmintization) is the giving of an anthelmintic drug (a wormer, dewormer, or drench) to a human or animals to rid them of helminths parasites, such as roundworm, flukes and tapeworm.
Risk groups for whipworm infections are children at preschool and school-aged children, people with specific high-risk jobs, women in reproductive and pregnant and breastfeeding women. The periodic treatment of the risk groups is done through either deworming campaigns or preventative chemotherapy.
Infection is most prevalent among children, and in North America, infection occurs frequently in immigrants from tropical or sub-tropical regions. It is estimated that 600–800 million people are infected worldwide, with 3.2 billion individuals at risk because they live in regions where this intestinal worm is common.
The World Health Organization (WHO) recommends mass deworming of children who live in endemic areas, in order to reduce morbidity by reducing the overall worm burden. [14] The WHO advises that worm infections adversely affect nutritional status, impair cognitive processes, and can cause conditions such as intestinal obstruction or lesions in ...
The pinworm has a worldwide distribution, [25] and is the cause of the most common helminthiasis (parasitic worm infection) in the United States, western Europe, and Oceania. [21] In the United States, a study by the Center of Disease Control reported an overall incidence rate of 11.4% among children. [21]
Children Without Worms (CWW) is a program of the Task Force for Global Health and envisions a world in which all at-risk people, specifically targeting children, are healthy and free of worm infections (helminthiases) so they can develop to their full potential.
Anthelmintic medication is also used in mass deworming campaigns of school-aged children in many developing countries. [ 2 ] [ 3 ] Anthelmintics are also used for mass deworming of livestock. The drugs of choice for soil-transmitted helminths are mebendazole and albendazole ; [ 4 ] for schistosomiasis and tapeworms it is praziquantel .
Furthermore, children with the highest counts of blood flukes also had the most malaria attacks. [25] Based on this study, Hartgers et al. drew a "cautious conclusion" that helminths make humans more susceptible to contracting malaria and experiencing some of its lighter symptoms, while actually protecting them from the worst symptoms.
