The "war has changed" against COVID-19 because of the highly contagious Delta variant, the U.S. Centers for Disease Control said, proposing a clearer message, mandatory vaccines for health workers and a return to universal masking.
An internal CDC document said the variant, first detected in India and now dominant across the globe, is as contagious as chickenpox and far more contagious than the common cold or flu. It can be passed on even by vaccinated people, and may cause more serious disease than earlier coronavirus strains.
