Second U.S. case of Omicron spotted in Minnesota, following travel to New York City

A second case of the Omicron variant has been identified in the U.S., detected in a Minnesota resident who had traveled to New York City for a convention attended by  tens of thousands of people. Health authorities in Minnesota said Thursday they're working with the Centers for Disease Control and Prevention and officials in New York City to investigate. 

The Minnesota man developed "mild symptoms" on November 22, after traveling to the Anime NYC 2021 convention in New York City, which hosted 53,000 attendees from November 19 through 21. 

While the first U.S. case of the Omicron variant was identified in a traveler from South Africa, Minnesota's case appears to be the first infection in the U.S. that does not involve travel abroad.
