title: [Socioeconomic aspects of subjects with imported malaria in the metropolitan area of São Paulo, Brazil. I. Characterization of the population and knowledge about the disease].
abstract: With a view to discovering the social and economic characteristics of people from endemic malarial areas of Brazil, 566 suspected malaria cases were studied at the S. Paulo City Metropolitan Region Malaria Laboratory. Data were obtained by means of the application of standardized questionnaires over the period from November 1986 to June 1987 to individuals with as history of transit to Brazil's endemic malarial region. Of the population studied, 345 (61.0%) lived in the endemic area; 479 (84.6%) were males, 513 (90.7%) were between 15 and 55 years old and 307 (54.2%) presented positive plasmodium haemoscopia. The analysis by educational level indicated that 486 (85.9%) had primary or secondary education; 109 (19.3%) worked in mineral extraction; 74 (13.2%) were farmers, and 46 (8.1%) were related to terrestrial transportation activities. With respect, to knowledge of the disease, 384 (67.8%) had at least 1 bout of malaria before and 491 (86.8%) associated the disease with the presence of the vector. Of the 221 residents in S. Paulo, 207 (93.7%), as well as 336 (97.4%) of those residing in the endemic area already know of the risks of infection prior to travelling through the area of transmission. The interval between the first symptoms and the seeking for medical care varied from 0 to 3 days in 386 cases (68.2%). The frequencies of the variables studied analysed according to the haemoscopic result and the place of residence, were statistically significant.
