Interventional Study of Nonpharmaceutical Measures to Prevent COVID-19 Aboard Cruise Ships

Cruise 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 c...
