Control of parasitic infections among school children in the peri-urban area of Botucatu, São Paulo, Brazil

Tide prevalence of intestinal parasitosis ivas investigated in a primaiy school located in Rubiâo Júnior, a peri-urban district of Botucatu, São Paulo slate, Brazil, in order to assess the effect of treatment and practical measures of prophylaxis in the control of parasitic infections among 7-to- 18-year-old school children of a low socio-economic status. The first series of parasitological examinations included 219 school children, ef which 123 (56.1 %) were found to be infected with one or more parasite species. Eighty- four children canying pathogenic parasites were submitted to various anti-parasitic treatment schedules. We re-evaluated 15 (89 %) students after 4 to 6 months post- chemotherapy. The results indicate that the combination of treatment with prophylactic measures has been successful in the control of parasitic infections, since reinfection rates were generally low (< 5-3 %), except for Giardia lamblia infections (18.6 %), and a marked reduction oti the prevalence rates was obsewed with a significant percentage of cure (> 73-1 %) in children infected with most parasite species. The reasons for the apparent failure in the control of infections caused by Hymenolepis nana and Strongyloides stercoralis are discussed.

Uso de nuevas herramientas para el control de triatominos en diferentes situaciones entomológicas en el continente americano

Se relatan los resultados obtenidos en el terreno seis meses y dos años post-tratamiento con las nuevas herramientas para el control de triatominos desarrolladas con apoyo de la OMS/TDR, o sea, a) pinturas insecticidas, una suspensión emulsionable de lenta liberación conteniendo el 8,3% de malathion, aplicada por rociamiento; b) potes fumígenos que, después de encendidos, echan humos que contienen cypermetrina y DDVP; c) cajas sensoras para detección de triatominos. Los ensayos en el terreno fueron realizados en Chile, Honduras y Paraguay contra tres especies principales de vectores de la enfermedad de Chagas - Triatoma infestans, T. dimidiata y Rhodnius prolixus, según el protocolo elaborado por un comité de expertos de la OMS. Los resultados indican que las pinturas insecticidas constituyen un eficaz medio de control de estos vectores en cualquiera de las condiciones estudiadas, sea en el domicilio, sea en el peridomicilio, manteniendo los porcentajes de infestación muy próximos a cero. Comparaciones preliminares de la técnica de cajas sensoras para detección de casas infestadas por triatominos, con la búsqueda hecha por personal entrenado (hora/hombre) indican esta última como la mas apropiada.

The control of Latin American trypanosomiasis

The author presents his personal point of view on the present situation of Chagas' disease control in Latin America countries. He compares the situation with African trypanosomiasis. He comments on the existence of cases in other Continents. He emphazises the success of the fighting against domiciliated triatomine bugs by using residual inseticides. He discusses other forms of Trypanosoma cruzi transmission.
