Why This Flu Season Is So Bad
The 2025–2026 flu season is already one of the most intense in decades, with flu-like illness reaching the highest levels seen in about 25 years. CDC data estimate that millions of people in the U.S. have already gotten sick, with hospitalizations and emergency visits rising quickly across many states.
Experts note that a particular strain, sometimes referred to as a “subclade K” variant, is driving much of this surge, spreading quickly and causing more severe symptoms in some patients. High circulation of other winter viruses—including COVID-19 and RSV—also means more people are getting sick at the same time, putting added strain on hospitals and clinics.
Cold vs Flu: Key Symptoms to Watch
Colds and flu can look similar at first, but there are important differences that help you know when to rest at home and when to call your doctor. The CDC explains that colds usually come on gradually and are milder, while flu tends to start suddenly and can leave you feeling very sick very quickly.
Typical cold symptoms:
Runny or stuffy nose
Sore throat
Mild to moderate cough
Mild fatigue
Low or no fever
Typical flu symptoms:
Sudden onset of high fever (often 100–102°F or higher)
Chills and sweats
Headache and eye pain
Intense body aches and weakness
Dry, hacking cough
Profound fatigue that can last for weeks
Flu is more likely than a simple cold to lead to complications such as pneumonia, sinus infections, or worsening of chronic conditions like asthma, COPD, and heart disease.
People at higher risk of severe flu include older adults, young children, pregnant people, and those with chronic illnesses or weakened immune systems.
When to Call Your Primary Care Doctor
You don’t need to handle cold and flu season alone. A primary care team can help determine whether you likely have a cold, flu, COVID-19, or something else, and guide you on testing, medication, and when you might need urgent care.
You should contact your doctor if:
Your fever is 101°F or higher and lasts more than 48–72 hours
You have trouble breathing, chest pain, or shortness of breath
Symptoms suddenly get worse after starting to improve
You are at higher risk (age 65+, pregnant, chronic heart/lung disease, diabetes, weakened immune system) and suspect flu
A child has fast breathing, poor fluid intake, or seems unusually sleepy or irritable
Antiviral medications for flu work best when started within 48 hours of symptom onset, so early contact with your primary care provider really matters. Practices with same- or next-day appointments and easy communication (text, portal, telehealth) make it much easier to be seen quickly and avoid unnecessary ER visits.
Why the Flu Vaccine Still Matters—Even Mid-Season
Even though flu activity is already high, the flu vaccine remains one of the most important tools for protecting yourself and your family. CDC data show that seasonal flu vaccines significantly reduce the risk of doctor visits, hospitalizations, and ICU stays, especially among older adults and people with chronic conditions.
For the 2025–2026 season, early analyses suggest that the flu vaccines offer meaningful protection, particularly against severe disease, even if the match to circulating strains is not perfect. Research consistently shows that vaccination can:
Lower your risk of getting the flu at all
Make illness milder if you do get infected
Reduce hospitalizations and serious complications
Protect vulnerable people around you, including infants, elders, and those with weakened immune systems
It is not too late to get your flu shot. The CDC recommends vaccination for everyone 6 months and older as long as flu viruses are circulating in the community. Given how intense this season already is, getting vaccinated now can still help protect you for the rest of winter.
What to Expect From the 2025–2026 Flu Shot
Flu vaccines for this season were updated to better match the strains scientists expected to circulate most widely. While no vaccine can provide 100% protection, current data and early studies indicate that the 2025–2026 flu shots are:
Moderately effective at preventing symptomatic flu
More strongly protective against severe illness and hospitalization
Safe for use in most adults and children, with side effects usually limited to mild arm soreness, fatigue, or low-grade fever
For people 65 and older, high-dose or adjuvanted flu vaccines are recommended because they generate a stronger immune response. Pregnant people are also strongly encouraged to get vaccinated, as the flu shot protects both them and their newborn for several months after birth.
If you’re unsure which flu vaccine is best for you or your child, your primary care provider can help you choose based on age, health status, and risk factors.
