Abstract
An outbreak of group A rotavirus infection resulted in gastroenteritis among disabled adults in an isolated rehabilitation institution in Kobe, Japan. Of the 95 residents, 16 were diagnosed with rotavirus illness. The causative agent was a single strain of typical human group A rotavirus belonging to VP7 serotype G2, VP4 genotype P[4], and NSP4 genotype A. Mean duration of stay was significantly longer for residents with rotavirus illness (22.1+/-11.8 years) than for residents without the disease (13.5+/-10.6 years; P=0.01). Age, sex, disability and location of resident rooms displayed no significant relationships with illness. These observations suggest that long-term residence in a closed community, which might be related to absence of immuno-stimulation, represents a risk factor for rotavirus illness.
