Helminthiasis. Tips for getting rid of unwelcome guests.

Helminthic parasites usually cause uncomplicated infections of the intestine. Complications can arise from nutritional competition between parasite and host, mechanical obstruction of the intestine or common bile duct (in ascariasis), and an overwhelming, fatal infection among immunocompromised hosts (in strongyloidiasis). Diagnosis is made by testing stool samples, except for Enterobius, which can often be seen in the perianal area. Treatment in uncomplicated cases is straightforward and easy. Several drugs are available, and the regimen depends on which parasites are present. However, none is safe for use in pregnant women.

Soil-transmitted helminthiasis in Myanmar and approximate costs for countrywide control.

Previous surveys in Myanmar indicate that soil-transmitted helminths (STH) are a significant public health problem. However the majority of these surveys are small scale or hospital based. To date there has been no countrywide assessment of the prevalence and intensity of STH infection. We conducted a survey (June 2002-June 2003) to assess the magnitude of STH infection in school age children in each of the different ecological areas of the country. In each area, five schools were selected and from each one, 50 children were randomly chosen. Parasitological and nutritional data were collected from each child. We found an overall prevalence of infection of 69%: 18% had a moderate-heavy intensity of infection, 22% were anaemic. A pilot exercise to treat 25,000 school age children in the 200 schools of Nyangdone Township tested the strategy before scaling up and to generate some rough costings. A crude calculation of the expenditure to buy and deliver the drugs, including the costs incurred in the teacher training, concluded that the cost per child was approximately 0.05 USD.

Soil-transmitted helminthiasis in Uganda: epidemiology and cost of control.

A country-wide description of the distribution of soil-transmitted helminths in Uganda is reported, based on data for 20-185 school-children from 271 schools. The overall prevalence of Ascaris lumbricoides, Trichuris trichiura and hookworm was 6.3%, 5.0% and 43.5%, respectively. The prevalence of A. lumbricoides and T. trichiura was unevenly distributed in the country with prevalence greatest in south-western Uganda whereas hookworm was generally more homogeneously distributed. Based on preliminary cost analysis of an ongoing school-based control programme, the financial delivery cost per school-child treated with albendazole is estimated to be between US dollar 0.04 and 0.08 in different districts.

Etiology and prophylaxis of helminthiasis in sheep in Burkina Faso.

Helminths of "Mossi" sheep from traditional livestock were investigated at three different seasons (humid, cold dry, and hot dry seasons) in the village of Donsin from the central land of Burkina Faso. Three prophylaxis plans using Fenbendazole were tested. Primary parasites identified were: Oesophagostomum sp., Trichostrongylus sp., and Haemonchus contortus. These parasites were noticed mainly during the rainy season with mean egg per gram (epg) numbers of 500 +/- 141.42 in August-September, at the end of the rainy season. At this same period, hematocrit (22%) and body weights (17 kg of live weight) (LW) were low. These values progressively increased to reach their highest levels (32% and 27 kg of LW respectively) in February. The prophylactic plan consisting of two treatments with oral drench of 5 mg/kg LW of Fenbendazole turned out to be the most efficacious and the most economical.
