Flu Season Arrives Early and with Force in Routt County & Beyond
Routt County residents are facing an earlier and potentially more severe flu season than last year, according to local health officials. Positive flu cases are currently 71% higher than at this point in the previous flu season, signaling a rapid increase in viral activity. This surge isn’t isolated to Steamboat Springs; cases are spiking across Colorado and drawing in travelers from multiple states.
Wastewater Monitoring Reveals Early Warning Signs
Routt County Public Health has been closely monitoring influenza A through wastewater analysis, detecting the virus as early as November 19th. Director Roberta Smith noted a significant spike on December 15th, indicating accelerating transmission. This wastewater surveillance provides a crucial early warning system, allowing public health officials to proactively prepare and inform the community.
“We are a couple of weeks earlier than last year in detecting it in the wastewater,” Smith explained. This early detection is prompting urgent recommendations for vaccination and preventative measures.
Exponential Growth and Vulnerable Populations
The rate of new flu cases is alarming health professionals. Lauren Bryan, infection prevention program manager at UCHealth Yampa Valley Medical Center, describes the growth as “exponential.” “Every day for the last week, I have thought this is exponential growth,” she stated. “The epidemiologic curve is not curved. It looks like an arrow going upward.”
Certain populations are particularly vulnerable to severe complications from the flu. Bryan emphasized the increased risk for young children, individuals 65 and older, pregnant women, and those with chronic health conditions. The flu is highly contagious, spreading easily one day *before* symptoms appear and for up to seven days *after* symptom onset. The virus can also survive on surfaces for up to 48 hours, increasing the risk of indirect transmission.
Vaccination Remains Key, Despite Imperfect Match
While the current flu vaccine isn’t a perfect match for the circulating strains, health officials strongly recommend vaccination. Bryan highlighted research showing the vaccine reduces the severity of illness, decreasing emergency room visits for flu by 72-75% in children and 32-39% in adults. Free flu shots are available at the Routt County Public Health Office for uninsured individuals or those whose insurance doesn’t cover the vaccine.
Influenza A Dominates, and Travel Plays a Role
Currently, 90% of confirmed flu cases in the past two weeks are influenza A, which tends to be more severe. It takes approximately two weeks for the body to develop adequate antibodies after vaccination, and vaccination rates in Routt County remain relatively low at 28%.
The approaching holiday season and increased travel are expected to exacerbate the situation. Bryan warned, “This is a particularly bad time of the year for flu to be hitting as people are gathering for Christmas/New Year’s, and that always increases the spread with the compounding factor of an immune-evading viral mutation.”
Statewide Surge and Hospitalizations on the Rise
The flu isn’t just a local issue; cases are surging statewide in Colorado. Smith reported an “acceleration in cases statewide,” with a corresponding increase in hospitalizations. UCHealth YVMC has treated patients ranging in age from 9 months to 90 years, including hospitalizations of residents from Routt County, other parts of Colorado, and out-of-state visitors.
UCHealth Urgent Care on Mid Valley Drive experienced its busiest day on record on December 26th, with 82 patients presenting with symptoms like cough, sore throat, and fever, some testing positive for the flu.
Where are the Travelers Coming From?
Analysis of positive flu tests at UCHealth YVMC reveals that 42% of individuals with the flu are from Colorado, with 78% of those being Routt County residents. The remaining 58% are from out of state, with the highest numbers originating from Texas, New York, Illinois, Florida, Tennessee, Mississippi, and Ohio. This highlights the role of tourism and travel in spreading the virus.
Symptoms and Prevention
Flu symptoms typically appear 1-4 days after exposure and include fever, cough, sore throat, runny or stuffy nose, muscle aches, headaches, and fatigue. Vomiting and diarrhea are more common in children. The CDPHE recommends staying home when sick, avoiding close contact with those who are coughing or sneezing, practicing frequent handwashing, and disinfecting common surfaces.
Looking Ahead: The Uncertainty of the Season
Predicting the severity of the flu season is challenging due to numerous variables. Smith acknowledged the difficulty in forecasting, noting that “tourism is probably the biggest fluctuation.” Memorial Regional Health in Craig has also seen a 9% increase in positive flu cases compared to last year, with two hospitalizations this month.
