Your mask might no longer be good enough for Galveston's biggest hospital
The Galveston County Daily News, January 27, 2022
The University of Texas Medical Branch requires at a minimum a surgical mask certified by the American Society of Testing and Materials, said Mary Ann DeMaet, the operation manager for infection control. “The variants became more contagious and easily spread,” DeMaet said. “We're seeing high transmissibility between individuals. So, we started requiring a higher-level mask. I think the cloth masks were OK in the beginning. But I think now that we know a little bit more, we probably need a higher-level mask to protect ourselves against the variants.”
