What should a captain of a cruise ship do if their is an outbreak of communicable disease at the port of call?

If a cruise ship captain encounters an outbreak of a communicable disease at the port of call, they should first ensure the health and safety of passengers and crew by following established protocols. This includes consulting with health authorities, implementing enhanced sanitation measures, and potentially postponing shore excursions. The captain should also communicate transparently with passengers about the situation and any necessary precautions. Finally, they should monitor any developments closely and be prepared to adjust the ship's itinerary as needed.
