CDC officials expressed concern in late December about a subvariant of omicron called XBB.1.5 circulating during the holidays. That variant caused most of the new cases being reported in certain regions of the U.S. According to CNBC, XBB.1.5 made up 27.6% of sequenced COVID cases for the week ending Jan. 7 compared to 18.3% the week prior.

Its spread is prompting local health officials to recommend masks in schools as kids return from the holiday break. The Wayne County Public Health Division is recommending masks in schools for two weeks — but stopped short of a mask mandate.

Health officials are also encouraging residents to get vaccinated and boosted. Students should stay home if they have symptoms like fever, diarrhea, vomiting or respiratory issues.
