December 2024 was declared a "high severity" flu season by the Centre for Disease Control (CDC), the worst in over half a decade. Hospitalization rates were up to 2.8 times higher than the median rates seen in the previous decade. That Christmas saw urgent care centers and emergency departments overwhelmed by significant patient volumes and persistent staff shortages, pushing healthcare systems to their limits. Families seeking medical care were faced with long wait times and uncertainty when the speed of diagnosis was key. Diagnostic tests that detect multiple viruses from one sample were critical to managing the surge and enabling healthcare providers to diagnose and provide targeted treatment quickly.
As the country heads into peak respiratory illness period, rapid and precise molecular diagnostic tests are no longer a luxury but a necessity to protect family health and make informed care decisions. Innovative companies like HealthTrack are expanding Americans' access to reliable next-morning molecular testing that brings access to precision diagnostics closer to families through their pediatrician, urgent care center, or local healthcare provider.
The Perfect Storm: What Families Faced During Holiday Season 2024
Converging Respiratory Threats
The declaration that the US was facing a "high severity" flu season in mid-December 2024 coincided with increased respiratory virus rates and persistently high COVID-19 circulation. During this period, it was estimated that over 70,000 children were hospitalized with RSV and nearly 46,000 with influenza, with the majority under 5. Overall, the season saw at least 24 million flu illnesses, 310,000 hospitalizations, and 13,000 flu-linked deaths, including 57 children.
As well as the severity of the flu, the holiday season amplified the risk of catching upper respiratory viruses. Increased travel, family gatherings, and more time spent inside provide the perfect transmission environment, with children, elderly relatives, and immunocompromised family members particularly at risk.
Healthcare System Strain and Family Impact
The strain faced by urgent care providers and emergency departments from severe flu numbers was compounded by further strains in the healthcare system. American healthcare systems were grappling with an estimated shortfall of more than 78,000 full-time registered nurses in 2025, exacerbating capacity challenges during the respiratory surge.
These pressures meant that parents and caregivers were facing hours-long waits with sick children, uncertainty about whether symptoms indicated flu, RSV, strep, or COVID-19, and anxiety about making the right treatment decisions. In that same year, nearly 5% of all hospital admissions faced 24-hour or longer waits for beds, a situation that had previously been rare.
The Cost of Delay
The use of traditional diagnostics during this period, such as clinical assessments or single-pathogen tests, left families without definitive answers. The consequences of this are significant; not only do patients receive delayed or incorrect treatment, families must make multiple visits to HCPs and clinics, perhaps leading to missed work or school, they may be susceptible to potential complications from untreated health issues, and unnecessary antibiotic prescriptions. December 2024 saw flu positivity rates increase by 12% in a single week and saw Americans face a health crisis, highlighting that families across the country need access to faster, more precise diagnostics.
Molecular Diagnostics for Family Healthcare
Moving Beyond Traditional Testing
So what are the limitations of older diagnostic tests? Rapid antigen testing, which has been used in the U.S since 2020, may miss infections, given that they have a lower sensitivity. Culture-based tests require days to get results, as these must be grown and examined in the lab. Finally, single-pathogen tests require providers and clinicians to have some idea of what virus they are testing for.
Parents need quick and definitive answers when seeking treatment for children and family members, to ensure that informed decisions can be made about work, childcare, or even isolation. The uncertainty that comes with these traditional tests is taxing, but new and innovative options exist.
Multiplex Molecular Testing
The growth of PCR-based molecular diagnostics in recent years has supported clinicians in diagnosis due to the tests' enhanced sensitivity in detecting pathogens. This has only been enhanced by the introduction of multiplex testing. Multiplex testing has the ability to test for multiple viruses from a single nasal swab. This helps to eliminate guesswork when sending off for labs, providing the complete picture that families and clinicians need.
Multiplex tests were vital during the 2024 flu season as they enabled HCPs and clinicians to rapidly identify the specific pathogen causing symptoms, guiding appropriate antiviral therapy, supportive care, or even over-the-counter treatments.
HealthTrack Bringing Precision Diagnostics Nationwide
HealthTrack, a precision molecular diagnostics laboratory, has recently partnered with USP to deliver rapid molecular diagnostics at scale across the United States. A new $45 million state-of-the-art laboratory at UPS LabPort in Louisville, Kentucky, which opened in September, means families in diverse communities across the nation can access the same precision testing that was once only available in metropolitan hospitals.
Not only has this partnership expanded access, it also supports HealthTrack in its mission of delivering next-morning infectious disease results, meaning clinicians can work with families and caregivers in selecting the correct treatment course in hours rather than days. Martin Price, the CEO at HealthTrack, noted the approach is "redefining infectious disease diagnostics."
Moreover, the expanding network of HealthTrack's testing labs across the US means families can access diagnostics through a number of touchpoints: their trusted pediatrician's office, local urgent care centers, or regional healthcare providers. This is particularly important for working parents and caregivers who need convenient and rapid results to make confident decisions in managing treatments and gauging expected recovery timelines. The shift in rapid and precise diagnostics helps to put diagnostic clarity and control back in parents' hands, with HealthTrack as a family health partner that not only supports clinicians but families in navigating the stress of childhood illness.
Conclusion: Preparing Families for the Respiratory Season of 2025–2026
As the country enters the 2025 flu season, the need for comprehensive diagnostics when healthcare systems face high demand reemerges. These challenges recur yearly and are becoming incredibly predictable. Expanded access to molecular diagnostics through companies like HealthTrack helps families respond more effectively to future respiratory illness surges.
Furthermore, the widespread adoption of rapid molecular diagnostics can reduce strain on emergency departments by enabling urgent care centers and primary care offices to manage respiratory illnesses more confidently.
HealthTrack's strategic expansion, through its state-of-the-art Louisville facility and UPS partnership, is bringing next-morning molecular diagnostics within reach of families nationwide, whether they seek care through their pediatrician, urgent care center, or local healthcare provider. This distributed diagnostic capacity creates a more resilient healthcare ecosystem that better serves families during both routine illness and surge periods.
