Coronavirus cases surged to new highs in parts of the Washington metropolitan area Tuesday, leading residents on a mad dash to find scarce home-testing kits and causing officials to warn of a need for tighter precautions and more hospital capacity.

Just in time for the holiday travel season, Maryland and the District are hitting unprecedented levels of new confirmed coronavirus cases and Virginia is climbing to daily levels not seen since September. The surge takes place as the omicron variant of the coronavirus seems to be driving a flare-up of infections nationally.
