1. U.S. authorities expand search for Omicron variant

U.S. public health officials are "actively looking" for the first cases of the Omicron coronavirus variant in the United States, Dr. Rochelle P. Walensky, the Centers for Disease Control and Prevention director, said at a White House news conference on Tuesday. Walensky said authorities at major international airports in New York, Atlanta, Newark, and San Francisco would expand the search for the new variant. Scientists are rushing to find out more about the strain's transmissibility and severity, but Dr. Anthony Fauci, the government's top infectious disease expert, said U.S. officials believe there is "good reason" to think existing vaccines will provide "some degree of protection." A federal judge on Tuesday blocked President Biden's vaccine mandate for health care workers from taking effect next week.
