Mask mandates returning to some college campuses

The final weeks of the college school year have been disrupted yet again by COVID-19 as universities bring back mask mandates, switch to online classes and scale back large gatherings in response to upticks in coronavirus infections.

Colleges in Washington, D.C., New York, Pennsylvania, Massachusetts, Connecticut and Texas have reimposed a range of virus measures, with Howard University moving to remote learning amid a surge in cases in the nation's capital.

Several Northeast cities have seen a rise in cases and hospitalizations in recent weeks, as the BA.2 sub variant of the omicron variant continues to rapidly spread throughout the U.S. In Washington, the city's COVID infection rate has more than doubled in April.

Besides American, Georgetown and George Washington University also reinstated their indoor mask mandates. Columbia University in New York City took a similar approach. Many, like Columbia, noted that their surveillance testing programs were finding more cases.
