My gut feeling is that an aircraft carrier would have enough space to set up a separate quarantine zone where the affected crew could be isolated and meals could be served to them there (yes, I’ve been on aircraft carriers). The rest of the crew would go on twice a day temperature checks and enhanced sanitation would become a priority. It would have at least shown that the commander was doing something to mitigate the problem while waiting for further instructions and proper protective gear to be delivered. His doing essentially nothing but complain suggests he didn’t even trust his crew to be resourceful and come up with interim solutions.
I agree - he could have taken some positive action instead of going all snowflake-bonkers.
