The omicron variant is fueling a surge during the holiday season that is leaving tri-state residents waiting on long COVID testing lines and racing to stores to grab last-minute at-home test kits. At least 192 omicron cases are confirmed in New York state with a fifth of those in the Big Apple, according to recent data -- though experts believe those numbers are significantly underreported. Gov. Kathy Hochul is urging the nearly 20% of New York adults yet to become fully vaccinated to do so. Experts still do not know the level of illness severity associated with omicron, but it is growing more clear how quickly this variant can spread. Omicron is now the dominant strain of coronavirus in the United States, according to data released on Monday by the Centers for Disease Control and Prevention.
