RESUMO
This descriptive study was developed in a State School, located in the city of Natal-RN, with the purpose to identify the knowledge and opinion of a group of adolescents about AIDS prevention. 30 questionnaires were applied and among the main obtained results, the authors found out that the adolescents are not well informed regarding this disease. Among the mentioned prevention methods they found the use of condom, but not in a systematic way by 50% of the population studied.

The Yellow Fever and Dengue Vector Control Program developed by the Superintendency for the Control of Endemic Diseases in the State of S. Paulo recommends Aedes aegypti and Aedes albopictus larval density monitoring in cities with domiciliar infestation. The sampling plan which has been applied in the countries of the Presidente Prudente region (SP- Brazil) since 1987 is described. The infestation is measured by using the Breteau Index. A sample of buildings is drawn, monthly and independently, in the infested cities, in which measurements are to be made. The sample is stratified and the elementary unit selection is made by using two-stage cluster sampling: of blocks and buildings. The sample sizes were defined using the coefficient of variation and the intraclass correlation as estimated for towns covered by the Regional Health Service of S. José do Rio Preto. These sizes must be corrected periodically in accordance with the values of the Breteau Index and its variance obtained in previous months.

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.
