In February 2011, three residents of a retirement community in Illinois were hospitalized for @entity697 . The admitting physicians ordered testing of stool specimens for several pathogens, including rotavirus. The hospital laboratory detected rotavirus antigen in specimens from each @entity1 , and the @entity580 control practitioner reported that information to the Cook County Department of Public Health. Two additional residents were hospitalized for @entity1902 shortly thereafter. The health department sent stool specimens from the five @entity1 to CDC for testing for rotavirus and norovirus. Rotavirus was detected in each specimen; norovirus was not detected. During a subsequent investigation, all available residents were queried regarding recent diarrheal symptoms. Preliminary data indicated that 22% of residents had confirmed or probable @entity6425 and 10 residents were hospitalized. In May 2011, another outbreak of @entity1902 was detected at a second retirement community in the county. On preliminary analysis, the overall attack rate in the second retirement community was 11%, and 20 residents were hospitalized. No @entity204 were identified in either outbreak. Based on preliminary results of the investigations and general knowledge of rotavirus transmission, within each community, rotavirus likely was transmitted from @entity1 to @entity1 via contaminated hands or fomites (e.g., environmental surfaces). The outbreaks lasted >= 4 weeks.
