Quick Read
- The U.S. is experiencing a severe flu season with 15 million reported cases as of mid-January 2026.

- Flu rates are ‘high’ or ‘very high’ in more than half of U.S. states, including New York, California, and New Jersey.

The United States is currently in the throes of an exceptionally severe and record-breaking flu season, prompting widespread concern among public health officials and medical professionals. With flu-related doctor’s visits at an all-time high and millions of people contracting the virus, the country has reported over 15 million cases and more than 9,000 deaths nationwide, including a distressing number of pediatric fatalities, as of mid-January 2026. This surge in illness and mortality has led experts to warn that the season is more severe than in recent years and is expected to worsen before any significant improvement.
Data from the Centers for Disease Control and Prevention (CDC) indicates that flu rates are categorized as “high” or “very high” across more than half of U.S. states. States like New York, California, Pennsylvania, and New Jersey are experiencing significant flu activity, contributing to the overall national burden. Dr. Suruchi Sood, an assistant professor at Johns Hopkins University, highlighted the severity, noting, “This flu season seems to be worse than previous flu seasons in that we are seeing more cases and we are seeing more hospitalizations associated with influenza than we have in previous years,” as reported by BuzzFeed.
Alarming Rise in Cases, Hospitalizations, and Deaths
The sheer volume of flu cases this season represents a substantial increase compared to previous years. Dr. Jeb Teichman, a former pediatrician and medical adviser for Families Fighting Flu, revealed that the U.S. has recorded 15 million flu cases so far this season, a significant jump from 9.1 million cases at the same point last year, according to BuzzFeed. This spike in infections has naturally led to a corresponding rise in hospitalizations and, tragically, deaths across the country. ABC News reported over 9,000 flu-related deaths and a near doubling of pediatric cases.
The impact on children has been particularly devastating. Massachusetts, for instance, has reported five pediatric flu-related deaths this season alone, with officials urging immediate attention for children exhibiting severe symptoms. “Children under the age of two are at higher risk. Parents should get their children ages six months and older vaccinated as soon as possible to decrease the risk of severe complications,” stated Massachusetts officials, as quoted by MassLive. Dr. Teichman further underscored the critical importance of vaccination, noting that in the last flu season, 90% of the 289 pediatric patients who succumbed to the flu were unvaccinated, and half of those children had no underlying high-risk conditions.
Understanding the Current Trends and Future Outlook
While some recent data might suggest a dip in positive flu test rates, experts caution against interpreting this as a sign that the flu has peaked. Positive flu test rates saw a decrease from 32.9% in late December to 24.7% in early January. However, Dr. Teichman explained that this drop is likely attributable to people not seeking care or testing during the holiday period. “What the CDC is saying is that people weren’t seeking care during the holidays,” he told BuzzFeed, suggesting that many individuals might have been sick but opted to recover at home without official diagnosis. Dr. Sood echoed this sentiment, adding that the true incidence of infection might be higher than reported due to less care-seeking during and immediately after the holidays.
Medical professionals anticipate a resurgence in cases as people return to work and school, and testing rates normalize. “It’s good to see that cases may be starting to tail off, but I would caution people that it’s still early days … we would want to see a continuing trend, a downward trend, before we let down our guard,” advised Dr. Daniel R. Kuritzkes, a senior physician in infectious diseases at Mass General Brigham. Dr. Teichman warned that the CDC expects flu cases to rise again, with the peak typically occurring in February. This challenging season is partly attributed to “a slight mismatch” between the predominant circulating flu strain and the composition of the current flu shot, which was formulated before the emergence of the new strain.
Prevention and the Enduring Importance of Vaccination
In light of the severe flu season, health experts are reiterating crucial preventative measures to help curb transmission and protect vulnerable populations. These recommendations include diligent handwashing, wearing masks in crowded indoor settings, maintaining distance from individuals who are coughing or sneezing, and avoiding contact with high-touch surfaces. “If you are not feeling well, stay home,” experts emphasize, urging individuals with flu symptoms such as fever, body aches, headaches, and sore throat to seek testing and treatment.
Despite the “slight mismatch” in the vaccine’s formulation and some evolving federal guidance, vaccination remains the cornerstone of protection against severe flu outcomes. While recent guidance from the Department of Health and Human Services may no longer unilaterally recommend flu vaccination, local health officials and infectious disease experts are strongly advocating for it. The Boston Public Health Commission, for example, “urges all city residents over the age of six months to get vaccinated and take preventative measures to protect against serious illness,” as reported by MassLive. Dr. Kuritzkes emphasized, “The most important thing is that if you have not yet gotten the vaccine, and many fewer people this year have been vaccinated than in past years, it is not too late.” The vaccine may not prevent infection entirely, but it significantly reduces the risk of severe illness, hospitalization, and death.
The current flu season presents a complex public health challenge, characterized by a potent circulating strain, a potential vaccine mismatch, and the behavioral impacts of holiday periods on data reporting. The combination of high case numbers, increased hospitalizations, and tragic pediatric deaths highlights the ongoing necessity for robust public health messaging, accessible vaccination programs, and consistent adherence to preventative measures, even as federal guidance may evolve. The emphasis from local health authorities and experts on vaccination as a critical tool for mitigating severe outcomes underscores the collective responsibility in navigating this severe health threat.
