(Reuters) - As coronavirus cases exploded across the world, federal medical workers tasked with screening incoming passengers at U.S. airports grew alarmed: Many were working without the most effective masks to protect them from getting sick themselves.
Screeners with the U.S. Centers for Disease Control and Prevention asked their supervisors this week to change official protocols and require stronger masks, according to an internal document reviewed by Reuters. On Friday evening, they learned their worst fears were realized: Two screeners, both working at Los Angeles International Airport (LAX), had tested positive for the virus.
