[Incidence of rotavirus in adults with diarrhea in Asunción, Paraguay].

From October 2001 to March 2004, 92 out of 533 (17.3%) fecal samples of patients over 18 years of age were positive for rotavirus. There were not differences of rotavirus incidence between age groups. Although in Paraguay, rotavirus infections in children less than 5 years old present a seasonal peak pattern (since June to October), in adults rotavirus was present throughout the year with the same frequency. Results presented here reinforce the notion that rotavirus should be considered in the differential diagnosis of diarrhea in adults.
