This article discusses options for the eradication of echinococcosis in Argentina and Chile. A programme proposal for the effective eradication of hydatidosis in the areas is presented. Some suggested components of the programme are epidemiological surveys, eradication of the infection in dogs,...

An epidemiological survey of echinococcosis (Echinococcus granulosus) was conducted in south-central Chile between 1992 and 1997. Indirect haemagglutination and ELISA tests were performed on 5556 apparently healthy people. Of these, 42 (0.8%) had positive results for both tests, giving a...

Echinococcosis remains a prevalent zoonotic disease in Chile. A survey of human cases showed persistent high notification rates in the extreme south of the country, with more than 30 hospitalizations per 100 000 people in 1989. The disease affects mostly young and middle-aged individuals (15 to 54...

Figures for the period 1969 to 1973 show Chile to have the fourth highest human hydatid morbidity in the world, with an annual frequency of 7 to 8 per 100,000. The actual incidence is probably much higher. The incidence was 48.4% in sheep, 47.7% in cattle and 23.1% in pigs, with higher values in...

A questionnaire about hydatidosis was sent to 37 farms in Tierra del Fuego Province, Chile, which has a population of 6,174 persons, 1,142,000 sheep and 30,946 cattle. During 1976, 35,947 sheep were slaughtered and 64.8% were infected with hydatid. Infection was more common in older sheep than in...

The Casoni intradermal test revealed that 78 of 510 people examined in rural Cautin Province, Chile, in 1971, were positive for hydatid. 4 of 73 dogs had Echinococcus granulosus infections and 35.8% of cattle slaughtered locally had hydatid. Although half the people in the survey had seen hydatid...
