Hospitals and healthcare systems across the country are reinstating mask requirements and visitor limitations in response to a concerning nationwide spike of respiratory illnesses, including COVID-19, influenza, and respiratory syncytial virus (RSV).
Mask Mandates Return as Hospitalizations Rise
With COVID-19 hospitalizations up 45% over the past month, many hospitals that had previously lifted mask mandates have brought them back. Some examples:
- Massachusetts General Hospital and several other Boston hospitals reinstated masks last week for all staff and visitors
- New York’s Health and Hospitals network, the nation’s largest public healthcare system, mandated masks again on December 15 for patients and staff
- In Maryland, where COVID hospitalizations have nearly doubled, hospitals across Baltimore were urged to bring back universal masking
- Beacon Health System hospitals in northern Indiana and Michigan have required masks since December 21
In addition to masks, many hospitals are also limiting visitors again to reduce transmission.

Flu, RSV Lead to Overcrowding Alongside COVID Uptick
The return of mask mandates comes amid a “tripledemic” of respiratory viruses circulating intensely nationwide. Cases of influenza have spiked to levels not seen this early in the season for over a decade, straining hospitals already overwhelmed by RSV and rising COVID-19 admissions.
In Maryland, over 1,500 people were hospitalized with the flu last week – eight times more than last year. Officials warn this could be among the worst flu seasons in recent memory. Hospitals in Central Maryland have reached 100% bed capacity multiple times this month.
“We have not seen this level of flu activity in December in over a decade,” said Jinlene Chan, Maryland’s deputy health secretary.
Pediatric hospital beds have been affected most acutely by RSV, which causes severe respiratory illness in very young children. RSV cases began rising unusually early this fall and remain extremely high nationwide.
New Restrictions Necessary but Insufficient, Officials Warn
Reinstated masking aims to alleviate record strain on short-staffed hospitals and protect vulnerable patients. However, health experts caution that more action is needed to curb viral spread as winter progresses.
“Universal masking in hospitals alone is not enough,” said Jessica Salinas, an infectious disease specialist at Johns Hopkins University. “To prevent crisis-level overcrowding, we urgently need multi-layered mitigation efforts, improved ventilation, increased access to antivirals, and public education.”
Salinas pointed out that European countries like France have retained baseline masking requirements and other precautions, enabling them to avoid the dramatic surges seen in the U.S.
“Masks should be normalized, not abandoned and sporadically reinstated only when it’s too late,” she said.
State officials are weighing potential new restrictions, like indoor masking advisories, as they monitor hospital capacity metrics carefully in the coming weeks.
Continued Vigilance Critical as Winter Progresses
With the situation rapidly evolving, experts emphasize that individual vigilance remains vital even as institutional policies shift. Wearing well-fitting masks in public indoor areas, staying home when sick, testing for COVID and flu, ensuring vaccinations are up to date, and maintaining good hand hygiene are critical personal precautions.
“Everyone has a role to play in protecting hospital capacity,” said Neil Jain, an emergency physician in Boston. “Avoiding infection means avoiding the ER.”
Many uncertainties around viral spread and hospital strain over the next few months necessitate continued caution from institutions and individuals alike. While short-term policy changes may provide relief when systems are overloaded, consistent evidence-based protocols for respiratory disease prevention are essential for sustainable, equitable population health. Achieving that level of pandemic resilience requires not just crisis management but proactive investment in public health infrastructure.
