I’m sure we’ve all been following the emerging story of the 2019-nCoV outbreak closely, with the third cases reported in the UK yesterday (pleased to see this is where you’d expect the UK to be based on Marc’s post earlier)! There’s been a small explosion of publications in the peer reviewed literature. I’ve chosen one slightly randomly to discuss today: a short modelling study providing some insight on the likely volume of unreported cases (very much the ice berg and not the tip!) and some sense of where this outbreak will end (it depends on how we respond, globally).
One of the key questions that we posed when this virus first emerged was is ‘silent’ transmission (that is transmission to others before symptoms become apparent) possible? And if it’s possible, is it the norm? A short letter published in yesterday’s New England Journal of Medicine answers the first part of that: silent transmission of 2019-nCoV is possible – but just how common is it?
I am interested, selfishly, in understanding the risk to Europe presented by the novel coronavirus (which now has a “working” name: 2019-nCoV; catchy isn’t it?!). It seems likely that there will be more imported cases, and possibly also some limited cross-transmission in Europe over the coming weeks.
I posted at the beginning of last week about the emergence of the as-yet-formally-unnamed novel coronavirus that has emerged in China. At that stage, it could have been a parochial anomaly in the annals of ID history. What a difference a week makes! Now we are looking at a rapidly emerging international outbreak!
