Cuomo, de Blasio urge mask-wearing but won't mandate it

New York City Mayor Bill de Blasio "strongly" urged even vaccinated people to start wearing masks indoors. Gov. Andrew Cuomo said unvaccinated transit employees in the metropolitan area would undergo weekly virus testing. But both Democrats on Monday resisted calls to impose new mask or vaccination requirements to counter a rapidly climbing number of new COVID-19 infections.

De Blasio explained that the city's "overwhelming strategic thrust" remains getting more people vaccinated. Cuomo said he lacks the legal authority to impose such local mandates on his own. 

"The Legislature would have to come back, they'd have to pass a law to do that. So I don't have any legal authority to mandate," Cuomo said of a mask mandate. "The best I can do is say I strongly recommend that they do that."

The mayor, at a separate briefing afterward, said city health officials are following a strategy based on "data and science."

"We thought the right mix was to heavily focus on vaccination to continue to climb the ladder, put more and more vaccine requirements in place, and to give a very clear message to all New Yorkers strongly recommending mask usage, regardless of vaccination status," he said.

Infection rates have been rising nationwide. The federal Centers for Disease Control and Prevention recently issued guidelines recommending that even vaccinated people wear masks indoors in parts of the U.S. where the delta variant is fueling infection surges.

Calls for a revived mask mandate in New York have grown louder as local numbers rise. 

An average of more than 2,400 people per day have tested positive for COVID-19 across New York state over the past week, up from around 300 new cases per day in late June. More than two dozen of the state's 62 counties met the CDC's recommendation threshold for masking up indoors Monday.

"Our leaders are moving slowly while the delta variant does anything but," the city's public advocate, Jumaane D. Williams, said in a prepared statement criticizing his two fellow Democrats. "Waiting to see if cases rise is equivalent to inviting them to do so. We need an indoor mask mandate now — we needed it a week ago before the CDC issued their directive."

New York City already requires face coverings in public schools and public transportation.

Cuomo on Monday announced that the vaccinate-or-be-tested policies already covering thousands of municipal employees would be extended to Metropolitan Transportation Authority and Port Authority employees working in New York facilities beginning Labor Day.

Northwell Health, which operates hospitals around the New York City area and employs 76,000 people, said Monday that workers who are not fully vaccinated by Aug. 16 will be required to be tested weekly for COVID-19. 

"As New York State's largest private employer and health care provider, we believe it is our obligation to set an example for the community by getting our team members vaccinated," the company said in a prepared statement.

The governor and mayor have each stressed vaccination as the key to fighting the pandemic. De Blasio announced last week that city employees would have to get coronavirus vaccines by mid-September or face weekly COVID-19 testing. Cuomo later announced a similar rule for state employees.
