A convergence of COVID-19, influenza, RSV, and other respiratory viruses has led to a spike in hospitalizations across much of the United States this winter. Fears of a “tripledemic” have put health systems on high alert as eased pandemic restrictions, holiday gatherings, and waning immunity contribute to the rise.
Erie, Pennsylvania Hospitals See Jump in Admissions for Respiratory Illnesses
Hospital admissions are up sharply in Erie, Pennsylvania for symptoms associated with COVID-19, RSV, flu, and other respiratory illnesses. Major local health systems like UPMC Hamot, AHN Saint Vincent Hospital, and Millcreek Community Hospital have reported significant patient influxes in recent weeks.
The post-holiday viral surge follows state and national trends, which health experts warn may continue elevating through January and February due to holiday travel and gatherings. Children appear especially impacted this season, with more pediatric hospital beds filled compared to prior years.
While COVID-19 remains a driver of admissions, RSV and influenza are contributing substantially to the patient volumes. Officials urge masking and vaccination to reduce spread.
Southern California Faces Triple Threat of Viruses With COVID, Flu, and RSV
Southern California is simultaneously battling surges of COVID-19, flu, and RSV in what doctors call a “tripledemic” of converging respiratory viruses. The situation mirrors trends being reported nationally of growing hospitalizations and warnings from the CDC.
Factors health experts cite include waning immunity from past COVID infections and vaccines, along with changed behaviors as pandemic restrictions have eased. People are socializing, traveling, and gathering more, causing viruses to spread. The winter season also tends to foster such transmission.
Hospitals are advising masking while indoors and getting updated COVID boosters along with annual flu shots. RSV poses challenges as there are no approved vaccines for adults. Officials emphasize preventative measures like hand washing while urging those at high risk to consult their doctors if falling ill.
Key Metrics on Rising Respiratory Viruses Post-Holidays
| Virus | % Increase in Hospitalizations | Age Groups Most Affected | Projected Peak |
|---|---|---|---|
| COVID-19 | +16% | 65+ | Mid-Jan to Mid-Feb |
| Influenza | +15% | 0-4, 5-24 | Late Jan to Feb
| RSV | +21% | 0-4 | Late Jan to Feb |

Health Networks Across U.S. See Patient Volumes Rise for Flu, RSV, and COVID-19
From New Jersey to Tennessee and Washington state, hospitals and health networks nationwide are reporting rising inpatient volumes associated with viral respiratory illnesses this winter. The influx follows holiday gatherings and comes amid waning immunity from past COVID infections and vaccines.
Facilities have needed to expand staffing and bed capacities, with some mandating masks again for staff and visitors to help control spread. continued viral activity is expected through January and February before tapering off in spring.
Doctors advise getting updated COVID boosters along with annual flu shots while continuing measures like masking and hand hygiene. RSV and other illness without inoculations remain concerning, especially for those at higher risk like infants, elderly, and immunocompromised.
CDC Warns of ‘Triple Threat’ With More COVID, Flu, and RSV Misery Ahead
In its latest weekly surveillance report, the CDC highlights the triple threat of surging COVID-19, influenza, and RSV across the country. Cases and hospitalizations for all three viruses worsened over the holidays, the agency warns, with indications more misery lies ahead this winter.
Factors health officials cite are holiday travel, family gatherings, school breaks, and changed behaviors as people have returned to socializing and events. These facilitate viral transmission while waning immunity also plays a role.
The CDC urges vaccination and continued precautions around masking and distancing to help mitigate spread. But with virus activity ramping up toward expected peaks in late January and February, severe outcomes seem probable absent sufficient population-level immunity.
Longer Term Outlook Hinges on Immunity and Emerging Variants
Looking beyond the coming weeks, the longer-range outlook depends greatly on levels of immunity and whether more dangerous new variants emerge. Continued viral evolution poses one of the largest wildcards.
Updated COVID boosters now match Omicron subvariants showing the most evasion of prior vaccine protections. But uptake of these bivalent shots remains low, leaving risks. And RSV and flu vaccines see limited public use despite annual recommendations.
Sustaining immunity across populations, both from infections and inoculations, gives the best hopes for controlling virus spread and preventing severe diseases. But pandemic fatigue has challenged many public health efforts. The course ahead relies on how people balance precautionary steps with restored normalcy.
