Recognition of leptospirosis in dengue-suspected cases during dengue outbreak in Ceará State, Brazil

چکیده
Dengue fever frequently presents with non specific symptoms, making it difficult to be distinguished from other acute febrile illnesses, including leptospirosis. Given this, serum samples from 82 patients with clinical features of dengue-like illness were evaluated for dengue infection by IgM-enzyme-linked immunosorbent assay (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR). Negative samples for dengue were tested for leptospirosis by IgM-ELISA and PCR. Dengue infection was detected in 35 patients. Six patients were positive to leptospirosis. This result shows that leptospirosis is underestimated in Ceará State, especially during epidemics of dengue with many reports, leading to an apparent low incidence of leptospirosis.

INTRODUCTION Dengue and leptospirosis are two febrile illnesses of great clinical and epidemiological importance in Brazil. Their significant degree of symptomatic similarity makes clinical diagnosis difficult. OBJECTIVE To diagnose leptospirosis differentially in patients with clinically suspected dengue.

متن کاملA New Possibility for Surveillance: Do We Identify All Cases of Leptospirosis?
Leptospirosis is a febrile disease with a typically underestimated global incidence, especially in regions where dengue is endemic. Therefore, it is difficult to accurately determine the number of leptospirosis cases in these areas, which contributes to significant under-reporting this disease. In this study, we estimated the number of possible leptospirosis cases among dengue-like cases that w...

With the aim of identifying the etiology of acute febrile illness in patients suspected of having dengue, yet with non reagent serum, a descriptive study was conducted with 144 people using secondary serum samples collected during convalescence. The study was conducted between January and May of 2008. All the exams were re-tested for dengue, which was confirmed in 11.8% (n = 17); the samples th...

Mayaro virus (MAYV) is frequently reported in Pan-Amazonia. The aim of this study was to investigate the circulation of alphaviruses during a dengue outbreak in the state of Mato Grosso, Brazil. Serum samples from dengue-suspected patients were subjected to multiplex semi-nested reverse transcriptase polymerase chain reaction for 11 flaviviruses and five alphaviruses, to nucleotide sequencing a...

BACKGROUND Dengue studies at the urban scale are scarce and required for guiding control efforts. In Brazil, the burden of dengue is high and challenges city public health administrations with limited resources. Here we studied the dynamics of a dengue epidemic in a single city. METHODS Serum samples from dengue suspected cases were collected and tested, from December 2012 and July 2013 in Gu...
