“…The median age of the patients was 14.9 years; twenty percent of patients were female and 80% were male. According to the Enteric Diseases Laboratory records, NoV infection were detected in 10 (35.7%) of the 28 fecal samples, confirming the large NoV outbreak occurring during the same period 4 . Mixed NoV and RV infections were not observed.…”

“…During summer 2010, the State of São Paulo (SP), located in southern area of the country, experienced a large gastroenteritis outbreak due to norovirus (NoV) 4 , a common viral pathogen associated with diarrhea, which has a marked seasonality during summer. The coastline area of SP was most greatly affected 4 , likely due to the increase of population density during the summer vacations and flooding in conjunction with the waterborne and seafood components of NoV transmission 5 .…”

“…The RT-PCR assay identified the G2P [4] genotype in 4 samples. Recently, a high prevalence of G2P [4] has been reported in Brazil and linked with the inclusion of the G1P [8] live oral RV vaccine in the Brazilian vaccination program 10 , suggesting that this monovalent vaccine possibly created conditions in which G2P [4] could acquire selective advantage over P [8] genotypes.…”

Alternatively, a temporal periodicity, within an approximately 10-year cyclic pattern of G2P [4] have been observed in Brazil 11 , and should be considered as an alternative explanation to the increased detection of this genotype since 2006.…”

Introduction: This study aimed to monitor the seasonality of rotavirus infection, and gain insight into the variability of Brazilian strains. Methods: A total of 28 stool samples were analyzed from 698 revised cases of gastroenteritis during a norovirus outbreak in the summer of 2010 in Guarujá, Brazil. Diagnosis was performed using enzyme-linked immunosorbent assay (ELISA), reverse transcription polymerase chain reaction (RT-PCR), and sequencing. Results: Rotavirus infection was detected in 17.9% (5/28) of samples; 4 samples were G2P[4] genotype, and one G2P[4]+P[6] genotype. G2 and P[4] sequences showed a genetic relationship to strains from India and Russia, respectively. Conclusions: The seasonal pattern of rotavirus may be a consequence of human activity apart from climate factors.

Along the coastal zone of the State of São Paulo, Brazil, diffuse discharges that flow directly to tourist beaches are responsible for introducing various pathogens into recreational waters. The objective of this study was to analyze, for the first time, the presence of protozoa (Cryptosporidium ssp and Giardia ssp), as well as human mastadenoviruses (HAdV–species C and F) and other species of adenoviruses (AdV) in beach drainage channels of Enseada and Perequê, municipality of Guarujá, São Paulo, Brazil. Protozoa were not detected in any sample over the course of the 11‐month study. In relation to HAdVs, 100% (n = 22) of the water samples presented contamination by at least one type of virus (C, D, or F species), suggesting potential risks to the public health following recreational exposure of beach users to these waters. Practitioner points First report on the presence of human adenoviruses in urban drainage channels in the coast of São Paulo State, Brazil. Urban surface water runoff is responsible for introducing human adenoviruses linked to disease outbreaks in areas of intense recreation. Cryptosporidium oocysts and Giardia cysts were below the limit of detection for all analyzed samples. However, all sites were positive for at least one of the viral species (HAdV–C, HAdV–D, or HAdV–F). Viral loads found in the water were similar to those commonly found in the wastewater.
