Control of hookworm infection by mass chemotherapy in Costa Rica

, : Control of hookworm infection by mass chemotherapy in Costa Rica. Revista de Biologia Tropical 20(2): 295-307

Tetrachloroethylene administered to 600 persons on a coffee plantation in San Jose Province, Costa Rica, in 4 doses, 1 to 3 ml. depending on age, 6 weeks apart, and subsequently in yearly doses during the following 4 years, reduced the prevalence of hookworm from 56% to 8%. Parasitic intensity was also reduced. Mild side effects were observed in 40% of the patients.

This may be due to a decrease in compartment volume, an increase in compartment content or external pressures. We report 4...
