During the Omicron era, rules requiring mask use in U.K. hospitals didn't prevent COVID-19 spread when there were no other pandemic precautions in place, a new study finds.
The end of COVID-19 emergency declarations in L.A. County brings new guidance on when to mask, quarantine or isolate and the reporting of new cases.
In the United Kingdom as in the United States, continuing mask mandates “became politicized,” Breathnach said. “Rather than people just flocking to their political tribe, we said, ‘Let’s see how much they actually work.’ The data were just sitting there.” On June 2, 2022, masking became optional for healthcare workers and visitors in most wards of St. George’s. However, on cancer wards, in dialysis suites and intensive care units, and at medical admissions, the mask mandate stayed in place. That allowed those areas of the hospital to serve as the study’s control group.
Breathnach said the stability of the group’s findings, even as a surge swept through London, gave them confidence that universal masking in hospitals had become hard to defend. Still, he said he understands why demands for continued masking would be the final fall-back for many people.
