Not at all... follow best practices... wash your hands (before and after restroom use, before and after food prep or touching money), stay home if you're sick and for employers emphasize this and work as well as possible around the issue. Don't panic.

In the end, it will spread, it will kill, and the only thing panic does is make things worse. If people washed their hands more and stayed home when sick instead of working through it, that's the most you probably should do.
