“…In Brazil, there are different frequencies of rotavirus detection throughout the year. In several regions of Brazil, as in the Southern region, a peak incidence was observed, mostly during winter months (Pereira et al 1993); in Rio Grande do Sul, also in Southern region, a higher incidence of rotavirus infection was observed during the summer months (Coiro et al 1983). In most states in the Northern region of the country, with tropical climates, seasonality has not been observed (Pereira et al 1993).…”

Key words: rotavirus -gastroenteritis -epidemiology -seasonality - Goiás -Brazil Diarrhoea is an important cause of morbidity in humans throughout the world, affecting mainly infants and children . Group A rotavirus is the most common cause of acute gastroenteritis in young children, causing a large number of hospitalizations (Pérez-Schael et al. 1999). Rotavirus is also associated with child mortality in several countries (Bern et al. 1992, Argüelles et al. 2000, Kapikian et al. 2001. This virus was detected for the first time in Brazil in 1976 (Linhares et al. 1977). After that description, several investigations were made and results demonstrated the relevance of rotavirus in the etiology of diarrhoea throughout the country (Rácz et al. 1988, Pereira et al. 1993, Leite et al. 1996.This study presents results from a rotavirus surveillance in Goiânia, Goiás. Our analysis was focused on the role of the virus in the diarrhoeal illness, as well as on ageprevalence and seasonality of rotavirus infection in the region. out diarrhoea from three different settings: children admitted to three hospitals (Hospital Materno Infantil, Hospital das Clínicas, and Hospital Lúcio Rebelo); children seen in outpatient clinics of Hospital Lúcio Rebelo, and children attending several day-care centers. Three or more liquid or semi-liquid daily evacuations were considered as diarrhoea, along with available medical information. Associated symptoms included vomit, fever and abdominal pain. The children enrolled in the study belonged to low socio-economic strata, according to the information provided by their parents/legal guardians. The faecal specimens were collected from the children only after a written consent was provided by parents/legal guardians. Also, ethical approval was obtained from the Ethics Committee on Research of the Federal University of Goiás. MATERIALS AND METHODS SubjectCharacteristics of the samples and of the childrenFrom 2,605 faecal specimens, 1,494 (57.4%) were collected from hospitalized patients. Of the remainder faecal specimens, 528 (20.3%) were obtained from children seen in outpatient clinics, and 583 (22.4%) in day-care centers. The investigation in hospitals began in 1986 and continued until 2000, except for the 1995-1997 period, when no samples were collected. In outpatient clinics the collection of the faecal specimens took place from 1986 to 1995, while in day-care centers samples were collected from 1989 to 1994. From the total number of fecal samples, 1,324 (50.8%) samples were collected from children with diarrhoea, and 1,246 (94.1%) of these children were hospitalized. From the remaining samples, 1,281 (49.2%) came from children who presented either with other symptoms than diarrhoea or with no symptoms. From those 480 (37.5%) were from outpatient clinics. All children with no symptoms were from day-care centers. Regarding the gender

“…The total number of hospitalizations of children under 5 years of age for diarrhea recorded by the various sources was divided by the birth cohort (21) to obtain the five-year cumulative incidence of hospitalization for diarrhea in each of the eight countries. The proportion of hospitalizations for rotavirus infection was based on published estimates for Argentina (5), Brazil (22)(23)(24)(25)(26)(27)(28), Chile (4), Mexico (29), and Venezuela (10). Because published estimates were not available for the Dominican Republic, Honduras, and Panama, the proportion of hospitalizations for diarrhea attributed to rotavirus for these countries was estimated based on other countries in Latin America and the Caribbean (4-6, 11, 29).…”

“…Por outro lado, índices bem mais elevados também já foram descritos. Num estudo realizado em Porto Alegre, Rio Grande do Sul, entre 1981 e 1982, rotavírus foi detectado em 41,8% das amostras (COIRO et al, 1983). Em outro estudo realizado entre crianças hospitalizadas em Salvador, Bahia, entre outubro de 1998 e dezembro de 1999, foi observada uma positividade de 35% (CAMPOS et al, 2002).…”

<span class="texto">A gastroenterite é uma das principais causas de morbidade entre crianças em países desenvolvidos e de mortalidade nos países em desenvolvimento. Os rotavírus são responsáveis pela maioria dos casos de diarréia e infectam praticamente todas as crianças nos primeiros 3 a 5 anos de vida. Os adenovírus entéricos são o segundo agente viral mais freqüentemente associado a diarréia, contudo sua epidemiologia não foi bem estabelecida. A presença de rotavírus e adenovírus foi investigada entre crianças da cidade do Rio de Janeiro, no período de janeiro de 1998 a dezembro de 2002. Amostras fecais de crianças com diarréia foram testadas para a presença do RNA de rotavírus por PAGE e para a presença de adenovírus por EIARA. Foram detectados rotavírus em 12% das crianças. A maior incidência da infecção por rotavírus foi observada nos meses de abril a setembro, os mais secos e frios do ano na região de estudo. A ocorrência de adenovírus foi observada em menor freqüência (6%), não apresentando padrão de sazonalidade definido.</span>
