COVID-19 is very contagious, and people can catch it from other people easily.  In the letter, Crozier said that the ship was too cramped to allow for sick sailors to do what the Centers for Disease Control and the Navy's own administration said people with COVID-19 should do: Keep away from other people for 14 days.  He asked for permission to let his sick sailors go ashore to Guam, where the ship was docked at the time, and go into quarantine there instead of on board the ship.  He copied part of a report about the Diamond Princess cruise ship, and said that even though the Diamond Princess'''s passengers had private rooms, more than 100 people still became infected.  He said the Theodore Roosevelt only had a few private rooms.
