[Considerations in an outbreak of viral acute gastroenteritis, Cisnădie 2009].

Frequent cause of morbidity and mortality in the whole world, viral gastroenteritis represent about 80% of infectious gastroenteritis. In non-industrialised countries it mostly affects small children,while in those industrialised it represents a significant cause of morbidity in all age groups. During 30.04--17.06.2009 we registered 315 cases of gastroenteritis in Cisnădie. All age groups were concerned, but 78.9% of cases were children less than 14 years old. We registered cases belonging to the same family. The clinical forms of the disease were mild or moderate. Identification of enteroviruses (Coxsackie A9 and non-typable EVNP) in 2 stool samples and in the water sample gathered from the residual water tank of the City Hospital in Cisnadie demonstrates the enterovirus circulation. 7 cases were confirmed with rotavirus. For the rotaviral etiology could also plead the information received from the District Hospital Sibiu concerning a series of cases diagnosed with rotaviral infection in children, during the months preceding the onset of this outbreak. Regarding the transmission of the agent we excluded a hydric outbreak, the most probable transmission being the direct one.
