STOCKHOLM, Aug. 6 (Xinhua) -- The spread of COVID-19 infection among young adults has increased in Sweden recently, said the Public Health Agency of Sweden on Thursday, which is in charge of advising national pandemic policies.
"It is a bad sign," said Anders Tegnell, state epidemiologist of the agency, on Thursday at a press conference, adding that the development is "worrying" because more vulnerable groups are at risk.
