Minnesota Joins Many Other States Adhering to CDC Call for All Hospitalized Flu Patients to be Tested for H5N1

U.S. Medical News: Concerns are mounting among health officials as reassorted strains of the H5N1 avian influenza virus - potentially resulting from recombination with seasonal flu strains - may already be circulating undetected. In response, Minnesota has joined other states in implementing updated guidelines issued by the U.S. Centers for Disease Control and Prevention (CDC), calling for rigorous testing of all hospitalized flu patients for the H5N1 virus.
Minnesota Joins Many Other States Adhering to CDC Call for All Hospitalized Flu Patients to be Tested for H5N1
The Minnesota Department of Health (MDH) recently announced that healthcare providers should perform advanced testing, specifically influenza A virus subtyping, on specimens from hospitalized flu patients.

U.S. Medical News report explores the rationale behind these updated guidelines and the broader implications of H5N1 monitoring in a landscape of elevated seasonal flu activity.
U.S. CDC Issues New Guidelines Amid Rising Concerns
The CDC's recommendations, issued last week, emphasize faster identification of H5N1 infections in humans. The agency's new advisory encourages testing within 24 hours of hospitalization for flu patients, particularly those in intensive care units. This effort aims to reduce delays in detecting avian influenza cases and improve the ability to contain potential outbreaks.

"Enhancing and expediting influenza A virus subtyping of specimens from hospitalized patients, especially from those in an ICU, can help avoid potential delays in identifying human infections with avian influenza A (H5) viruses," the U.S. CDC stated in its advisory.
Delays in diagnosis can have significant consequences, particularly during a time when healthcare systems are burdened by unprecedented levels of seasonal flu.
In 2024, the United States reported 66 confirmed human cases of H5N1. While most of these cases were mild, one fatality was recorded. With fears of reassorted strains capable of human-to-human transmission, the U.S. CDC's heightened vigilance underscores the need to stay ahead of the virus.
MDH Implements Advisory for Minnesota Providers
In Minnesota, the MDH is taking proactive steps to ensure that healthcare providers adhere to the U.S. CDC's guidance. Providers are urged to conduct subtyping on influenza A-positive specimens, especially for hospitalized patients with severe respiratory illness. According to MDH, this targeted testing approach is not an indication of increased risk to the general public but rather a precautionary measure to support optimal patient care and timely case in
vestigations.
"This guidance does not reflect an increased concern for or risk of human cases," MDH clarified. "Acceleration of subtyping specifically aims to prevent delays in identifying human infections with A(H5N1) viruses, support optimal patient care, and facilitate timely infection control and case investigation."
Although the risk of bird flu remains low for the general population, the MDH is urging healthcare providers to remain vigilant, especially as seasonal flu cases continue to decline after reaching unprecedented peaks in recent weeks.
National Efforts to Combat Bird Flu
The U.S. CDC’s updated guidelines are part of a broader national effort to address avian influenza. The U.S. Department of Agriculture (USDA) has allocated $1.5 billion to combat bird flu outbreaks, deploying over 300 personnel to manage the crisis and protect poultry and dairy herds. Additionally, the USDA has announced plans to rebuild its vaccine stockpile for poultry, preparing for worst-case scenarios.
The human toll of bird flu has been relatively low, with nearly 70 confirmed cases in the United States since April 2024, most of which involved farmworkers exposed to infected poultry. However, three cases were reported without a clear source of exposure, raising questions about potential gaps in monitoring.
Nirav Shah, the U.S. CDC's principal deputy director, highlighted the importance of swift testing during a recent press call. "No surveillance system detects 100% of cases," Shah noted, adding, "What we need is to shift to a system that tells us what's happening in the moment."
How Does Subtyping Work?
Subtyping is a laboratory process that identifies the specific strain of influenza A present in a patient’s sample. This method is critical for distinguishing between seasonal flu strains and non-seasonal viruses like H5N1. Faster results from subtyping can help health officials trace sources of infection, administer appropriate treatments, and manage contacts who may also be at risk.
Prior to the CDC’s latest recommendations, hospitals typically sent batches of samples for subtyping every few days. The new guidelines call for expedited testing to ensure timely identification of avian influenza cases.
Conclusion: Vigilance Is Key
As Minnesota aligns with other states in enhancing bird flu monitoring, it reflects a broader commitment to public health and preparedness. While the risk of H5N1 to the general public remains low, the potential emergence of reassorted strains capable of human-to-human transmission warrants caution. By expediting testing and strengthening surveillance systems, health officials aim to mitigate the risks posed by avian influenza.
This heightened focus on early detection, combined with national investments in vaccine technology and response protocols, underscores the need for ongoing vigilance. For now, seasonal flu remains the most likely cause of flu-like illnesses, but the possibility of avian influenza cases highlights the importance of proactive measures in a rapidly evolving public health landscape.
