Philadelphia became the first major US city to reinstate its indoor mask mandate on Monday after reporting a sharp increase in coronavirus infections, with the city’s top health official saying she wanted to forestall a potential new wave driven by an omicron subvariant, Associated Press reported.
Confirmed COVID-19 cases have risen more than 50% in 10 days, the threshold at which the city’s guidelines call for people to wear masks indoors, said Dr. Cheryl Bettigole, the health commissioner. Health officials believe the recent spike is being driven by the highly transmissible BA.2 subvariant of omicron, which has spread rapidly throughout Europe and Asia, and has become dominant in the US in recent weeks.
“If we fail to act now, knowing that every previous wave of infections has been followed by a wave of hospitalizations, and then a wave of deaths, it will be too late for many of our residents,” said Bettigole, noting about 750 Philadelphia residents died in the wintertime omicron outbreak. “This is our chance to get ahead of the pandemic, to put our masks on until we have more information about the severity of this new variant.”
Health inspectors will begin enforcing the mask mandate at city businesses on April 18, according to the Associated Press.
Most states and cities dropped their masking requirements in February and early March following new guidelines from the US Centers for Disease Control and Prevention that put less focus on case counts and more on hospital capacity. The CDC said at that time that with the virus in retreat, most Americans could safely take off their masks.
Philadelphia ended its indoor mask mandate March 2, and Bettigole acknowledged “it was wonderful to feel that sense of normalcy again.”
Confirmed cases have since risen to more than 140 per day — still a fraction of what Philadelphia saw at the height of the omicron surge — while only 46 patients are in the hospital with COVID-19. The CDC says community spread in Philadelphia remains low, a level at which the agency says that masking can be optional.
The restaurant industry pushed back against the city’s reimposed mask mandate, saying workers will bear the brunt of customer anger over the new rules.
“This announcement is a major blow to thousands of small businesses and other operators in the city who were hoping this spring would be the start of recovery,” said Ben Fileccia, senior director of operations at the Pennsylvania Restaurant & Lodging Association, Associated Press reported.
PolicyLab at Children’s Hospital of Philadelphia said Friday that while it expects some increased transmission in the northern US over the next several weeks, hospital admissions have remained low and “our team advises against required masking given that hospital capacity is good.”
Bettigole said requiring people to mask up will help restaurants and other businesses stay open, while a huge new wave of COVID-19 would keep customers at home. She said hospital capacity was just one factor that went into her decision to reinstate the mandate, Associated Press reported.
“I sincerely wish we didn’t have to do this again,” Bettigole said. “But I am very worried about our vulnerable neighbors and loved ones.”
