Governments around the world are struggling to decide when people can return to work. The coronavirus pandemic has closed businesses and factories and damaged economies. Workers in some nonessential businesses returned to their jobs Monday in Spain. South Korean officials, however, are warning that new infections could appear if restrictions are lifted. And officials in the United States are debating when businesses can reopen in the world’s biggest economy. The decisions are difficult to make, especially on a national level. Some areas are hit harder and at different times than others. Britain, Japan, parts of the United States and other places are still seeing daily increases of deaths or infections. Both Italy and Spain have seen drops in recent days. The U.S. has more confirmed cases and deaths than any other nation.
