Europe seems to have the resources to deal with the epidemic outbreaks, so far at least, I can't really see there being to much of an issue for those wishing to a few weeks/months touring Europe, sure you might not be able to go to all the places you want and you may need to take long diversions to avoid blackspots.
The real issues will those that wish travel the globe, Turkey has apparently closed its borders with Iran, other countries are likely to follow suit and as the epidemic becomes pandemic then more countries will be closing their borders with their neighbours.
Beside you all should of been preparing for the zombie apocalypse so a simple outbreak of Corona virus should be child's play
