This prospective study was conducted in Salvador, a large city in north-east Brazil, where two epidemics were previously recorded (DEN-1 and DEN-2). We obtained the seroprevalence and 1-year incidence of dengue infections in the population of 30 sampling areas of Salvador and analysed the relationship between intensity of viral circulation, standard of living and vector density. High seroprevalence (68.7%) and annual incidence (70.6%) of infection for one or both circulating serotypes (DEN-1 and DEN-2) were found. High rates of transmission were observed in all studied areas, from the highest to the lowest socio-economic status. The mean PI (Premise Index) for Aedes aegypti was 7.4% (range 0.27–25.6%). Even in the areas with the lowest PI (£ 3%) the observed seroincidence was 54.6%. These findings highlighted the existence of a silent epidemic during a period perceived by the Health Services as of low endemicity, indicating the strength and speed of dengue transmission in the city of Salvador.Submitted by Suelen Reis (suelen_suzane@hotmail.com) on 2012-12-12T16:42:54Z No. of bitstreams: 1 j.1365-3156.2002.00930.x.pdf: 78052 bytes, checksum: e846d4af256df12f6bd5639fcb3b6a5e (MD5)Made available in DSpace on 2012-12-12T16:42:54Z (GMT).
