A second U.S. case of COVID-19 caused by the Omicron variant has been picked up by genetic testing in Minnesota.
The man, from Hennepin County, Minn., fell ill on Nov. 22 after attending the Anime NYC 2021 conference at the Javits Center in New York City a few days before. He sought testing on Nov. 24. His symptoms have resolved, according to a press release on the case from the Minnesota Department of Health. The man was fully vaccinated, the department said.
He was advised to isolate from others, but it’s unclear if he had contact with anyone else before he learning he was infected.
“This news is concerning, but it is not a surprise,” said Governor Tim Walz in a news release. “We know that this virus is highly infectious and moves quickly throughout the world. Minnesotans know what to do to keep each other safe now — get the vaccine, get tested, wear a mask indoors, and get a booster. Together, we can fight this virus and help keep Minnesotans safe,”
The first case of COVID-19 caused by Omicron was detected Dec. 1 in California. That case was in a traveler who had recently returned from South Africa.
