What type of reports must be kept for the past month prior to inspection?

The requirement to maintain DNBI (Disease Non-Battle Injury) weekly reports for the month preceding an inspection is rooted in the need to monitor and assess crew health and safety on naval vessels. DNBI reports track non-battle related illnesses and injuries, providing critical data on health trends and potential outbreaks of contagious diseases among crew members.

By keeping these reports, commanders and health personnel can identify patterns or spikes in certain health issues that may need addressing. This data is essential for ensuring that preventive measures are in place, thereby enhancing overall crew readiness and health.

On the other hand, operational reports, medical readiness inspection reports, and volunteer activity reports, while valuable for different aspects of ship operations, do not specifically focus on the health surveillance needed to comply with sanitation inspection requirements. Therefore, they are not prioritized for retention in the month leading up to an inspection like the DNBI weekly reports are.
