Emerg Infect Dis. 2024 May;30(5):1030-1033. doi: 10.3201/eid3005.231364.ABSTRACTCruise ships carrying COVID-19-vaccinated populations applied near-identical nonpharmaceutical measures during July-November 2021; passenger masking was not applied on 2 ships. Infection risk for masked passengers was 14.58 times lower than for unmasked passengers and 19.61 times lower than in the community. Unmasked passengers' risk was slightly lower than community risk.PMID:38666667 | DOI:10.3201/eid3005.231364
