4 Things You Must Know About the New Severe Flu Variant
What to know as the “super flu” continues to spread.
As we move through peak flu season, hearing about friends and family who are sick and the sound of coughs and sneezes filling the air is typical for late January. However, the recent surge in flu activity and the announcement of a newly emerged flu variant for the 2025–2026 flu season may feel alarming.
This phenomenon, often referred to as a “super flu,” has raised some concerns about how to keep yourself and your loved ones healthy and safe this season.
What Is the New Flu Variant?
The newly identified flu variant, known as subclade K, has gained attention due to its rapid, widespread transmission. While the phrase “super flu” is not a medical term, the public has coined this name due to the strain’s severity and high activity. According to the CDC, this season has seen the highest number of flu cases in more than 30 years, with at least 11 million infections reported nationwide, leading to significant hospitalizations and deaths. Flu activity has reached high or very high levels in most U.S. states, and current data suggest this strain is responsible for approximately 90% of flu cases.
4 Things You Must Know About the New Severe Flu
1. Symptoms May Mimic This Season’s Common Illnesses
The symptoms of the new flu variant are similar to those of the traditional flu and common cold, including fever, cough, sore throat, body aches, fatigue, and congestion. Because symptoms overlap, testing and medical evaluation are important for an accurate diagnosis. Early treatment can help reduce the severity and duration of symptoms.
2. Hand Hygiene Still Matters
Frequent handwashing is one of the most effective ways to prevent the spread of flu viruses. Because the virus spreads through respiratory droplets and contact with contaminated surfaces, keeping your hands clean can help reduce your risk of infection.

3. Symptoms May Last Longer Than Typical Flu
Some patients are experiencing prolonged symptoms, including lingering fatigue and cough. It’s important to remain calm, but if symptoms worsen or become severe, seek immediate medical care.
4. Certain Groups Are at Higher Risk
Older adults, young children, pregnant individuals, and those with chronic medical conditions are more likely to experience complications if diagnosed with the flu. If you belong to a higher-risk group and experience flu symptoms, seek medical attention promptly.
