According to the Guardian, epidemiologist Jonathan Quick says,
The worst-case scenario is looking increasingly likely. We’ve now seen cases on six continents, apparently “silent” – that is, at least partly asymptomatic – chains of human-to-human transmission both inside and outside China, with additional countries reporting cases within the last week – bringing the total to 47 – and new, accelerating outbreaks in Iran, Italy and South Korea. If it becomes a pandemic, the questions are, how bad will it get and how long will it last? The case fatality rate – the proportion of cases that are fatal – has been just over 2%, much less than it was for Sars, but 20 times that of seasonal flu.
