$AAPL Health threat of any pathogen is measured by three things: 1) Vector 2) Contagion 3) Virulence Novel Corona Virus has an airborne vector and appears to be very contagious with a two week incubation. This means it can spread fast. But. It isn't particularly virulent. That is to say, most people's immune systems fight it off pretty well which means a low mortality rate despite being fast spreading. While a significant threat to vulnerable populations (folks with compromised or understrength immune systems) it isn't a huge threat to most folks.
