In the absence of significant improvements in reporting, adjustments to outbreak reporting thresholds may be needed to account for incomplete voluntary AGE reporting and more rapidly implement control measures, including more rigorous cleaning protocols and an aggressive hand hygiene campaign for both passengers and crew. Twelve of these tested positive for genogroup II norovirus via RT-qPCR, and all were negative for Genogroup I norovirus [19]. The questionnaire also did not assess whether case passengers who changed their hygiene practices did so before or after becoming ill, so a temporal relationship between hygiene practices and illness could not be established. A review of outbreaks of foodborne disease associated with passenger ships: evidence for risk management. Summary: Norovirus is the leading cause of acute gastroenteritis in the United States and is estimated to cause nearly 21 million cases annually. How common is norovirus on cruise ships?

Case passengers were significantly more likely to have an ill cabin mate (relative risk [RR] = 3.0; P < .01) and to have witnessed vomiting during boarding (RR = 2.8; P = .01). That changed on Sept. 18, 2019, when the CDC was informed that one of the cruise ships was sailing into U.S. jurisdiction.

The episode of public vomiting on day 1 of the cruise in the high-traffic guest relations area provides further evidence that passengers who were ill during embarkation likely introduced norovirus onto the ship and helped seed the outbreak. The crew's low attack rate may be because relatively few of the 859 crew had direct contact with passengers, including separate sleeping and dining areas and separate areas for boarding and exiting the ship. Noroviruses can also be transmitted through aerosolized vomitus [3, 4]. Of these, 95 (40%) did not report to the infirmary.
