Virus masks, apps: The race is on to avoid hidden carriers
NEW YORK (AP) — The race to protect people against becoming infected by unwitting coronavirus carriers is intensifying as a new study shows the illness may be spread by people without symptoms. Governments are now pitted against each other in the race to buy protective gear and medical equipment. New questions are also emerging about who should wear masks, get temperature checks or even be permitted to go outside. In New York state, deaths doubled just in 72 hours to more than 1,900, while globally, the toll from the virus is over 47,000. In Wuhan, China, where it all began, authorities are keeping tabs on who is allowed to move around with a smartphone app that shows healthy people with a green symbol.
