Most of the U.S. will see significant growth in COVID-19 cases during the next four weeks, according to the latest forecasting models by the PolicyLab at Children's Hospital of Philadelphia.
Large metropolitan areas, especially those in the Northeast, are already seeing a major increase in cases following Thanksgiving, and that trend is expected to continue.
"Why? Simply stated, the large amount of Thanksgiving travel and gatherings undermined the nation's pandemic footing and has elevated disease burden in areas of the country that were fortunate to have lower case rates before the holidays," the forecasters wrote.
Case numbers in New York City are expected to double throughout December, the forecasters said. Similar growth could happen across Boston, Philadelphia, and Baltimore.
