Facing a winter surge in COVID-19 infections, New York Gov. Kathy Hochul announced Friday that masks will be required in all indoor public places unless the businesses or venues implement a vaccine requirement.
Hochul said the decision to impose a mask mandate was based on the state's weekly seven-day case rate, as well as increasing hospitalizations.
The mask mandate applies to both patrons and staff and will be in effect from Monday to Jan. 15, after which the state will reevaluate.
"We're entering a time of uncertainty and we could either plateau here or our cases could get out of control," Hochul warned at a public appearance in New York City.
New York joins several states with similar indoor mask mandates, including Washington, Oregon, Illinois, New Mexico, Nevada and Hawaii.
An average of roughly 9,740 people tested positive for COVID-19 over the seven days through Dec. 8 in New York, a 38% increase from the previous seven days, according to The Associated Press's review of state data.
The surge is especially pronounced in some areas of upstate New York, which has accounted for nearly three-fourths of confirmed COVID-19 deaths in hospitals since August.
"We are heading upward in a direction that I no longer find sustainable," Hochul said.
Hochul announced the mask mandate at a social service agency on the west side of Manhattan, where most people already wear masks. New York City requires vaccinations for indoor restaurant dining, entertainment and gyms, so those venues will be unaffected by the new rule.
Several upstate New York counties have recently enacted mask mandates as well, including Erie County, which includes Buffalo.
Hochul said violators could face civil and criminal penalties, including a maximum fine of $1,000. Local health departments will be in charge of enforcing the requirements.
