Diagnosed cases are now ~6000 with ~60 fatalities if my reading is accurate. Coronavirus is a large group including 'common colds' with many residing in other animals. This one jumped to humans in 2019 December in Wuhan China. Likely in a 'wet market' (common here but readers may not have had the experience). Possibly from snakes or bats. It is being compared to 2003 SARS virus (another corona) which in total infected ~8000 and killed ~80 before human-transmission chain was ended in 2004. We might make very early comparisons that 2019-nCoV is more transmissible but less lethal. But they would be very early comparisons. My understanding of SARS is that it had only a few hours of latency (during which pre-symptomatic infected individuals can transfer virus by aerosol and direct contact), but this virus may have ~10 days of latency. In a globally jet-travel-connected world, that would stand as a large distinction. It has been suggested that Wuhan was slow to recognize this risk. One media report says Wuhan mayor says 5 million people left that city before the gates were closed. Sucks to be him... Context: now is Spring Festival in China, largest annual migration on Earth. Context: most of that migration is domestic. Most developing viral infections will will be within China. Global health care will be faced with leakage and in many countries they are well up to the task. In a broader view, any virus that jumps host species has a window to evolve different patterns of infectivity and lethality. Jump to humans and that window includes anti-bacterially medicated hosts, and other viral infections in hosts that may mix DNA. It would only improbably be by such stirring that 2019-nCoV could become that whopper that clickbaits suggest it already is. Might become. Other recent viral contestants have not. Media difficulties: I have seen images of stacked corpses and I doubt their veracity. All might see images of empty streets in Chinese cities, and those are realistic. As they would be any year because Spring Festival is when almost everything shuts down. == We all should manage contact hygiene as we ought to be doing anyway. In US for example where seasonal influenza has taken its typical ~8000. Beyond that we can observe how well this new player makes its species jump.
