Human leptospirosis: a twenty-nine-year serological study in São Paulo, Brazil

Abstract

A retrospective study of 9,335 cases of human leptospirosis in the state of São Paulo, Brazil, diagnosed between 1969 and 1997 showed that the disease is endemic throughout the state. Middle-aged adults, with a range of 20-39 years, were most frequently infected (32.40%). The mean annual incidence was 0.53 per 100,000 population and the disease was more frequent in males (87.0%). Cases occurred mainly in January to April each year. A peak was observed in 1991 and 1996 which rainfall average was 159.9 and 160.3, respectively. These data emphasize the potential public health importance of leptospirosis in the state of São Paulo, Brazil.

Análise espacial do risco de leptospirose canina na Vila Pantanal, Curitiba, Paraná

“…Os moradores dessas regiões acabam despejando seu lixo onde lhes for conveniente, ficando de fácil acesso para os cães e roedores, o que cria condições favoráveis para a disseminação da leptospirose. Diversos trabalhos, que também analisaram o contexto ambiental de casos de leptospirose, verificaram que as maiores taxas de incidência ocorreram nas regiões ao redor das zonas de acumulação de lixo e de deficiência de infraestrutura básica, apontando para a combinação de fatores socioambientais, ainda que a relação não seja direta (Barcellos e Sabroza 2000;Figueiredo et al 2001, Romero et al 2003, Dias et al 2007, Soares et al 2010.…”

“…These serovars represent the most prevalent serogroups in SP (Sakata et al 1992, Romero et al 2003, Romero & Yasuda 2006. Serovar Andamana was also used since it was isolated from CSF in Brazil (Corrêa et al 1971).…”
