Sadly, the spread of this virus worldwide(major cities etc) is inevitable due to it's nature and the interconnectivity of modern life. As mentioned above, it seems to be for the most part unpleasant, but not deadly. That said, if there are underlying health issues then the mortality rate would climb. Practice good and sensible hygiene when out and about and don't stress yourself overly as this won't help and might well hinder as it surpasses the immune system.
