Estudio seroepidemiológico de la hidatidosis y triquinosis humana, mediante la reacción de hemaglutinación indirecta, en la Comuna de San Juan de la Costa: Osorno, X Región, Chile; 1990-1991 / Seroepidemiological study of human hydatidosis and trichinosis, by means of indirect hemagglutination reaction, in San Juan de la Costa County, X Region, Chile: 1990-1991

RESUMO

San Juan de la costa County (40-45' South lat., 73-19' West long) is located in the Osorno province, South of Chile. Its population is 8,486 inhabitants. The basic economic activities are agriculture, cattle raising, timber production and manufacture of wood and coal. According to official reports, the incidence of human hydatidosis and trichinosis in this locality in 1989 were 24 and 59% respectively. In order to contribute to a better knowledge of the epidemiology of human hydatidosis and trichinosis in San Juan de la Costa County, an indirect hemagglutination test (IHAT) for these parasitoses was performed to 511 randomized people. Nine (1.8%) individuals resulted positive for hydatidosis and twenty four (4.7%) were positive for trichinosis. Some considerations on the corresponding phrophylactic meaures are proposed
