Why Hasn’t the U.S. Found More Omicron Cases?
Just a day after South African scientists first announced the discovery of the Omicron variant, Europe reported its first case: The new coronavirus variant was in Belgium. Before the weekend was out, Australia, Britain, Canada, Denmark, Germany, Israel, Italy and other countries had all found cases. But in the United States, scientists kept searching. “If we start seeing a variant popping up in multiple countries across the world, usually my intuition is that it’s already here,” said Taj Azarian, a genomic epidemiologist at the University of Central Florida.
