THE coronavirus attack has so far been much less deadly than the Spanish flu of a century ago. That had affected 500 million people worldwide, about 27 per cent of the world’s population of the time, and had a death rate of about 10 per cent among those affected. (Estimates of death vary greatly; this is a sort of mean). In India alone 17 million people are estimated by some to have died because of it. By contrast the coronavirus has affected, to date, less than two lakh people worldwide, and has a death rate of about three per cent among those affected.
