The college says every one of the positive tests it has sequenced so far has been the Omicron variant. The Omicron COVID-19 variant (purple) now accounts for 3% of U.S. Covid cases, up from less than one percent last week. The school has reported 930 Covid cases in recent days, with almost all of the cases sequenced found to be of the new variant. All of the Omicron cases are among people who are fully vaccinated, the school reports. It is the first country to ban travel from the UK and Denmark due to the Omicron variant.
