CDC says it is extending order, which was set to expire on 18 April, to allow more time to study Omicron subvariant
The Biden administration announced on Wednesday that it is extending the US nationwide mask requirement for public transit for 15 days as it monitors an uptick in Covid-19 cases.
The Centers for Disease Control and Prevention (CDC) said it was extending the order, which was set to expire on 18 April, until 3 May to allow more time to study the BA.2 Omicron subvariant that is now responsible for the vast majority of cases in the US.
