Concerned worried and prepared is having a mask, swimming goggles if that is something that makes you personally feel more comfortable. Maybe 500 tins of beans.
Panic is sharing extreme articles, worst case doom implying infection scenarios. Suggesting governments are conspiring to play down these worst case doom scenarios. Suggesting it is a Bio-weapon or man made virus, that it is in some way related to HIV.

As for the folks in Wuhan, they probably aren’t panicking either. They have a problem, they might have to stay isolated or are getting treatment, if they act accordingly they might not get the virus and if they do they currently appear to have a 97% chance of not dying.
