A New Mask Debate Emerges as the Delta Variant Spreads
Health officials are grappling with how to prevent potential COVID-19 outbreaks from the delta variant that is spreading rapidly across the U.S.
Concern over the highly transmissible delta strain prompted Los Angeles County this week to recommend that all people wear masks indoors, even if they’re vaccinated. The World Health Organization (WHO) has also encouraged fully vaccinated people to continue using masks.
But the Centers for Disease Control and Prevention (CDC) has not signaled any plans to revise its mask guidance, with Biden administration officials and some experts say that fully vaccinated Americans are safe from all existing COVID-19 variants.
