In a White House news briefing, Dr Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said, "We knew it was just a matter of time before the first case of omicron would be detected in the United States.”

Meanwhile, President Biden will extend until mid-March a requirement that travellers wear masks on airplanes, trains and buses and at airports and transit stations, a person familiar with the decision said Wednesday night.
The move to extend the mandate, which was set to expire on Jan. 18, is part of a much broader winter strategy for combating Covid-19 that Biden is to announce on Thursday, during a visit to the National Institutes of Health. The strategy will also include a new requirement that international travellers be tested for Covid-19 one day before departing for the United States, according to officials at the Centers for Disease Control and Prevention. The mask mandate extension was first reported by Reuters on Wednesday.
