What is Social Distancing?
Updated: Apr 27
We don’t yet know the full ramifications of the novel coronavirus. But three crucial facts have become clear in the first months of this extraordinary global event. And what they add up to is not an invocation to stay calm, as so many politicians around the globe are incessantly suggesting; it is, on the contrary, the case for changing our behavior in radical ways—right now.
The first fact is that, at least in the initial stages, documented cases of COVID-19 seem to increase in exponential fashion. On the 23rd of January, China’s Hubei province, which contains the city of Wuhan, had 444 confirmed COVID-19 cases. A week later, by the 30th of January, it had 4,903 cases. Another week later, by the 6th of February, it had 22,112.\
The second fact is that this disease is deadlier than the flu, to which the honestly ill-informed and the wantonly irresponsible insist on comparing it. Early guesstimates, made before data were widely available, suggested that the fatality rate for the coronavirus might wind up being about 1 percent. If that guess proves true, the coronavirus is 10 times as deadly as the flu.
But there is reason to fear that the fatality rate could be much higher. According to the World Health Organization, the current case fatality rate—a common measure of what portion of confirmed patients die from a particular disease—stands at 3.4 percent. This figure could be an overstatement, because mild cases of the disease are less likely to be diagnosed. Or it could be an understatement, because many patients have already been diagnosed with the virus but have not yet recovered (and may still die).
