The Navy and Marine Corps Public Health Center was tasked with providing public health support for the outbreak investigation and conducting data analysis in alignment with its core public health mission. Data were collected as part of a coordinated public health outbreak investigation conducted by the Navy to bring the outbreak under control, ensure the well-being of the crew, assess the spread and effects of SARS-CoV-2, and implement measures to return the crew to work safely. Under Navy public health support criteria, the intent of the outbreak investigation was to mitigate spread, inform decision making, gather information for use in other outbreaks, and decrease the effect on the health of the crew. This project was deemed to be nonresearch with respect to the use of human subject information and was exempt from review by the institutional review board as an emergency public health outbreak investigation.
