Columbia University is again requiring its students to mask up in classrooms, with public health experts urging caution as COVID-19 case numbers climb across the U.S.
The university's head of COVID-19 protocols over the weekend announced the change, citing increased infections in the local area. The disease's resurgence in New York City after cases had fallen sharply earlier this year was punctuated on Sunday when Mayor Eric Adams tested positive for the virus.
The virus is also flaring elsewhere around the U.S. More than two dozen states across the country reported a jump in cases over the last eight days, although hospitalizations and deaths have not seen a commensurate rise. Nearly 1 million Americans have died of COVID-19, with an average of 500 people succumbing to the disease every day, according to the Centers for Disease Control and Prevention.
