RESUMO
In presecuting the investigations on the epidemiology of toxoplasmosis in Chile, a new series of serological surveys has been performed during 1982-1989 in 10 urban and 25 periurban-rural localities form the regions VII, VIII and IX of the country [34-41'-39-38' South lat.]. In 9.758, randomly selected, apparently helathy persons, and indirect hemagglutination test [IHAT] for toxoplasmosis was carried out. The age of these individuals [4.203 males and 5.555 females] varied between 4 and 84 years. The exmined persons represent a 0.33% of the total population of the three studied regions. IHAT titers of 1> ou = 16 were regarded as positive. The global prevalence for positive IHAT was 45.5% [50.5% in men and 41.7% in women]. A higher proportion of positive tests was observed in urban areas [47.0%] than in periurban-rural sections [33.3%]. An increasing prevalence with age was also observed. Only 5[0.05%] persons had IHATtiters higher than 11000
