U.S. health authorities on Monday shortened the recommended isolation time for Americans with asymptomatic cases of Covid-19 to five days from the previous guidance of 10 days.
The Omicron variant was estimated to be 2.9% of the Covid-19 variants circulating in the United States as of Dec. 11, according to data from the U.S. Centers for Disease Control and Prevention (CDC).
Americans fully vaccinated against Covid-19 should go back to wearing masks in indoor public places in regions where the coronavirus and especially the Delta variant are spreading rapidly, U.S. authorities said on Tuesday.
The U.S. CDC said on Thursday it will no longer require travelers to wear masks in outdoor transit hubs and in outdoor spaces on ferries, buses and trolleys, due to the lower risk of coronavirus transmission outdoors.
Fully vaccinated New Yorkers will be able to do almost anything in New York state without wearing a mask as of Wednesday.
