Cruise ship norovirus attack rate suggests threshold for declaring outbreak may need adjustment. MedPage Today (3/23, Smith) reported, "A norovirus outbreak on a cruise ship resulted in a 15% attack rate despite early detection and aggressive measures to contain illness, the CDC reported" in a paper published online March 22 in the journal Clinical Infectious Diseases. "The outbreak, in January 2009, sickened 236 of the 1,532 passengers who completed a CDC questionnaire during the cruise, according to Mary Wikswo, MPH, and colleagues at the CDC." Only about 60% of the sick passengers presented to the ship's infirmary for medical care, however. For that reason, the study authors concluded that "the threshold for declaring an outbreak may need to be adjusted to account for poor voluntary reporting of acute gastroenteritis."
