Initial reportsindicated 12 residents and 1 staff member hadexperienced gastrointestinal illness; 3 residentshad been hospitalised. An epidemiological andenvironmental investigation sought details ofillness, food consumption, food purchasingpractices and social activities for the 3 day periodprior to the onset of illness in the first case. In total,18 (16 residents, 2 nursing staff) were ultimatelylinked to this outbreak (Figure). The predominantsymptoms were diarrhoea in 18 cases (100%) andvomiting in 10 cases (55.5%). Of the 15 cases forwhom the time of onset was available, the medianincubation period was 45.5 hours (range: 12 to 94hours).
