Sweden should have done more to combat the coronavirus, the epidemiologist behind a national strategy that avoided the strict lockdowns seen in many other countries said on Wednesday. Sweden has a lower COVID-19 mortality rate than European countries such as Britain, Spain and Italy which enforced stringent lockdowns. “Yes, I think we could have done better in what we did in Sweden, clearly,” Tegnell, the chief epidemiologist at the Public Health Agency, told Swedish radio.
