Resumen
Objective The objective of this study was to evaluate the real size of the epidemics registered in the urban area of the county of Santa Bárbara D'Oeste, SP, Brazil, from April to June, 1995. The measurement of the epidemiological validity of the official surveillance system criteria and its positive predicted value were adopted as specific goals. Methods A sero-epidemiological survey was carried out over a sample of 1,113 sera from citizens of Santa Barbara D 'Oeste, through a systematic random sampling of houses, five months after the end of the epidemics. Infection rates were compared with the infestation indexes by Aedes aegipty and the notified cases amongst the county sections. The importance of submitting patients with clinical suspicion of dengue to laboratory tests was discussed. Results and Discussion It was found that infection rates by dengue virus varied in the same direction and proportion as the presence of Aedes aegipty larvae reported by the "Breteau Index", as well as the number of cases reported by the official notifiable diseases surveillance system during the epidemics. A prevalence of 630 by 100 thousand inhabitants was found, a 15-fold rate when compared to the laboratory positive sera from cases detected by the surveillance system during the epidemics. A retrospective comparison with the surveillance reports, using serological results as a gold standard, also showed that the majority of dengue specific serum-positive individuals were not detected during the epidemics, otherwise cases that did not present serological reaction were notified exhibiting a low positive predictive value of clinical diagnosis (15,6). 33 6 566 574 Alves, M.C.G.P., Gurgel, S.M., Almeida, M.M.C.R.R., Plano amostral para cálcule de densidade larvária de Aedes aegypti e Aaedes albopictus no Estado de São Paulo, Brasil (1991) Rev Saúde Pública, 25, pp. 251-256 (1996) Bol Inform, 11 (47). , maio Dietz, V.J., Gubler, D.J., Rigau-Perez, J.G., Pinheiro, F., Schatzmayr, H.G., Bailey, R., Epidemic dengue 1 in Brazil, 1986: Evaluation of a clinically based dengue surveillance system (1990) Am J Epidemiol, 131, pp. 693-700 Figueiredo, L.T.M., Rosa, A.P.A.T., Fiorillo, A.M., Níveis de anticorpos para arbovírus em indivíduos da região de Ribeirão Preto, SP (Brasil) (1986) Rev Saúde Pública, 20, pp. 204-211 Figueiredo, L.T.M., (1994) Estudos Sobre o Dengue Em Ribeiräo Preto 1990-1993, , [dissertação] Ribeirão Preto (SP): Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo; Figueiredo, L.T.M., Abe Owa, M., Carlucci, R.H., Dal Fabero, A.L., Mello, N.Vd., Capuano, D.M., Encuesta serológica sobre el dengue en Ribeirão Preto, São Paulo, Brasil (1995) Bol Oficina Sanit Panam, 118, pp. 499-509 Guzmán, M.G., Kouri, G.P., Bravo, J., Soler, M., Vasquez, S., Morier, L., Dengue hemorrhagic fever in Cuba, 1981: A retrospective seroepidemiologic study (1990) Am J Trop Med Hyg, 42, pp. 179-184 Halstead, S.P., Global epidemiology of dengue hemorrhagic fever (1990) Southeast Asian J Trop Med Public Health, 21, pp. 636-641 Johnson, K.M., Halstead, S.B., Cohen, S.N., Hemorrhagic fever of Southeast Asia and South America: A comparative appraisal (1967) Prog Med Virol, 9, pp. 105-158 Kuno, G., Gómez, I., Gubler, D.J., Detecting artificial antidengue IgM immune complexes using an enzyme-linked immunosorbent assay (1987) Am J Trop Med Hyg, 36, pp. 153-159 (1987) Dengue Hemorrágico: Diagnóstico, Tratamento e Controle, , Genebra Resurgimiento del dengue en las Américas (1997) Bol Epidemiol, 18 (2) Shope, R.E., Sather, G.E., Arboviruses (1979) Diagnostic Procedures for Viral, Rickettsial and Chlamydial Infections. 5th Ed., pp. 767-814. , Lennete EH, Schimidt NJ, editors Washington (DC): American Public Health Association (1997) Inf Epidemiol SUS, 6 (1) Theiler, M., Downs, W.C., (1973) The Arthropod-borne Viruses of Vertebrates, pp. 62-91. , New Haven: Yale University Press Tirado, M.G.G., Flores, G.K., Gonzalez, J.B., Silva, L.C., Ramudo, S., Encuesta serológica nacional a virus dengue.
