Stressing out about it right now won’t do you or anyone else any good. Just keep an ear to the ground for news updates. If they still have hantavirus under control and quarantined on the ship, it’s a good sign that it will stay contained there.

I don’t think we have another global pandemic on our hands, but you should take precautions now just in case - especially if it makes you feel less anxious about it. Wearing a mask in public costs you very little in terms of effort and is far more socially acceptable post-Covid.
