• New York Gov. Kathy Hochul announced a statewide mandate that will require masks to be worn in all indoor public places unless businesses or venues have implemented a vaccine requirement. 
• The new mandate goes into effect on Dec. 13, 2021.
• It will be effective until Jan. 15, 2022, at which point the state will reassess its effectiveness based on Covid-related public health conditions. 

New York Gov. Kathy Hochul on Friday announced a statewide mask mandate for all indoor public places unless the businesses or venues already have a vaccine requirement in place. 

The new mandate goes into effect Monday through Jan. 15, 2022, at which point the state will reassess its effectiveness based on Covid-related public health conditions. 

Noncompliant businesses could be subject to both civil and criminal penalties with a maximum fine of $1,000 per violation. Local health departments will enforce the mandate. 

It is the latest move by the governor to combat the spread of the highly mutated omicron Covid variant, which has been confirmed in at least 20 cases across the state as of Thursday. The measure also serves as "added layers of mitigation" during the holiday season when family and friends are spending more time indoors.    

"The temporary measures I am taking today will help accomplish this through the holiday season," Hochul said in a statement. "We shouldn't have reached the point where we are confronted with a winter surge, especially with the vaccine at our disposal, and I share many New Yorkers' frustration that we are not past this pandemic yet."

The decision was based on the state's weekly seven-day case rate and increasing hospitalization numbers. Since Thanksgiving, that average has spiked by 43% and hospitalizations have risen by 29%. 

Hochul added that state vaccination rates have climbed 2% since the Thanksgiving weekend, bringing the total to more than 80% of fully vaccinated New Yorkers.

On Thursday, the governor also said nearly 500,000 booster doses were distributed in the state in the past week, a 50% increase from the previous week.

However, she noted that the "uptick is not fast enough to completely curb the spread of the virus, particularly among communities with low vaccination coverage."

"I have warned for weeks that additional steps could be necessary, and now we are at that point based upon three metrics: increasing cases, reduced hospital capacity and insufficient vaccination rates in certain areas," Hochul said in the statement, adding the mask mandate "will no longer be necessary" if "others will follow suit" and get vaccinated.

New York state health commissioner Dr. Mary Bassett said vaccinations and masks are necessary to slow the spread of the omicron variant.

"Community spread requires a community-minded solution, as the omicron variant emerges and the overwhelmingly dominant delta variant continues to circulate," Bassett said. "We have the tools we need to protect against the virus, and now we must ensure we use them."

Despite the rising concern about omicron, Bassett emphasized that the delta variant remains the primary driver of high case rates and hospitalizations in the state and across the U.S. 

Delta still accounts for more than 99% of all genetically sequenced positive samples in the U.S., CDC Director Dr. Rochelle Walenksy said during a White House press briefing on Tuesday.

New York joins several other states with mask mandates, including New Mexico, Nevada and Hawaii. 

What's more, a number of local governments where omicron has been detected have bolstered Covid protocols in recent weeks. 

New York City, for instance, issued an advisory strongly recommending that everyone wear masks indoors in public places at all times regardless of vaccination status.
