New concerns are arising today as more and more kids that have returned to school are coming home sick. In most cases, however, it’s not COVID-19, but the common cold, which can have similar but less severe symptoms.

Meanwhile, health officials are on edge as people take to bars to celebrate St. Patrick’s Day.
