WASHINGTON: The US Centers for Disease Control and Prevention on Friday revised its guidance for Americans on wearing masks to protect against COVID-19, recommending donning"the most protective mask you can" while stopping short of advocating nationwide usage of N95 respirators.
N95 masks may be considered for use in places like transit"when greater protection is needed or desired", it added. "Masking is a critical public health tool to prevent the spread of COVID-19, and it is important to remember that any mask is better than no mask," the CDC added. The CDC last May announced that fully vaccinated people could shed their face coverings, as COVID-19 cases were then on the decline. But in July, the CDC said fully vaccinated people should wear masks in indoor public places in regions where COVID-19 was spreading rapidly. The CDC said this week 99.5 per cent of US counties currently are covered by the mask recommendation.
Los Angeles County, the nation's most populous, on Monday will require some employers to provide"medical-grade" masks - surgical masks, KF94, KN95s or N95s - to workers at high risk of contracting a COVID-19 infection on the job.
