The Omicron variant of SARS-CoV-2 is the latest strain of the coronavirus to be designated a "variant of concern" by the World Health Organization: more and more countries are reporting cases, and it has an unusual combination of mutations that may enable it to spread faster. Scientists are also trying to determine whether the current vaccines are effective against it.
At least 10 cases have been reported across five states: Hawaii, New York, Colorado, Minnesota, and California. Some local leaders say Omicron is likely spreading in their states, after spotting cases not linked to international travel.
