The other three-quarters

摘要

How to PREVNT new surges in cases? How to reopen businesses in an era of social distancing? How to revive prone economies? These are the questions preoccupying most of the rich world, where covid-19's first wave, at least, is mercifully ebbing. But elsewhere the pandemic remains far from any crest. Brazil is adding around 25,000 new confirmed cases a day, more than the United States. Russia and India are not far behind, with 8,000 or so apiece. All told, poorer countries account for some three-quarters of the 100,000 or so new cases detected around the world each day.
