[Rotavirus detection in feces of children with acute diarrhea]

Abstract:

:OBJECTIVE: To determine the prevalence of rotavirus in the etiology of acute diarrhea in children from Natal city, RN, Brazil and investigate the existence or not of a seasonal distribution of this pathogen in our environment.METHODS: Fecal samples from 1,903 children (boys and girls) with ages ranging from 1 month to 10 years, living in Natal-RN, who presented acute diarrhea episodes in a period from January 1996 to December 1998, were analyzed. We searched viral particles directly in the feces by a passive agglutination reaction using anti-rotavirus specific-group monoclonal antibodies coated latex particles.RESULTS: 151 children (7.9%) of the studied population presented a positive reaction, revealing the presence of rotavirus particles in feces. Considering, however, only the children (ages from 1 to 24 months) who are more susceptible to rotavirus infection, we verified that from 1,065 examined children, 136 of them (12.8%) presented positive reaction for rotavirus, and the great majority of all children with positive reaction (96.3%) had ages ranging from 6 to 24 months. Analysis of the distribution of the cases of rotavirus infection in the three year revealed that the incidence of infection was higher in July, August, and September.CONCLUSIONS: The results indicated rotavirus infections have an important role in the etiology of acute diarrhea cases. The majority of the acute diarrhea cases positive for rotavirus occurred during the first two years of life, reaching mainly children from 6 to 24 months, with the highest incidence of infection during the months of July, August, and September.
