I don't think we can know yet. It's infected around 300 people, 6 of whom have died, putting a mortality rate of around 2%. Thats not as bad as SARS, which was 10%, but its early. SARS ended up being restricted to around 8000 people, mostly concentrated in China, though eventually spreading to dozens of countries, but its impossible to say how far and wide this one could spread, especially given that the outbreak is occuring on the eve of Chinese New Year. According to some of the sources I've found online, coronaviruses tend to be much less easily spread from human to human than something like the flu, but just a few days ago officials were saying they didn't think this virus was transmissible between humans, which they now have confirmed is in fact possible, so clearly its a very fast developing situation.
