The "new flu" getting attention is a fast-spreading variant of influenza A called H3N2 subclade K, a mutated strain that has become dominant globally and is linked to a surprisingly severe 2025-2026 flu season, causing higher-than-normal activity, especially as it's somewhat mismatched with the current vaccine.
 

Why is everyone getting a cough?

In addition to cases of flu, COVID-19, and RSV (respiratory syncytial virus), Perl has noted more respiratory infections this season due to adenovirus (detailed by the CDC) and human metapneumovirus (hMPV) — both which can cause the common cold and lead to a nasty cough.

What does the RSV virus feel like?

RSV often feels like a bad cold, with a runny nose, cough, sneezing, and maybe a low fever, but it can get more intense, especially for babies, older adults, and those with health issues, bringing on significant wheezing, shortness of breath, and trouble eating, potentially leading to pneumonia or bronchiolitis. In young infants, it can manifest as extreme fussiness, fatigue, and pauses in breathing.

The "new flu strain" for the 2025-2026 season is a rapidly spreading variant of Influenza A(H3N2) called "subclade K," causing more severe illness and earlier, faster surges in cases than usual, leading to a potentially worse-than-average season despite moderate vaccine effectiveness against severe outcomes, notes CIDRAP, Stanford University, and Nature. This subclade K has mutations that allow it to partially evade immunity, especially in older adults, but current vaccines still offer significant protection against severe disease, say The BMJ, Centers for Disease Control and Prevention | CDC (.gov), and The BMJ.
 

What is the new upper respiratory virus called?

Human Metapneumovirus (HMPV) Human metapneumovirus (HMPV) is a virus that usually causes symptoms similar to a cold. You might cough or wheeze, have a runny nose or a sore throat.

Lingering coughs are often due to an unresolved infection, virus or flare-up of an underlying health condition—such as lung disease or asthma—whereas a chronic cough can be a sign of asthma, COPD, acid reflux, gastroesophageal reflux disease (GERD) or upper airway cough syndrome.

How to tell if a cough is viral or bacterial?

Telling viral from bacterial coughs is tricky, but viral coughs often start gradually with a runny nose and clear mucus, improving in 7-10 days, while bacterial coughs tend to worsen after initial improvement, last over 10 days, or involve thick, colored (yellow/green) mucus, severe symptoms like high fever, trouble breathing, or localized pain, requiring a doctor for diagnosis and antibiotics. 

What is a red flag in coughing?

These signs can point to infections, lung cancer, heart failure, or other severe conditions requiring urgent evaluation.

Since early December, H3N2 subclade K has been the dominant flu strain in the United States. It is the first time since the 2016-2017 flu season that an H3N2 virus has been dominant. Because of how rapidly subclade K has spread in the United States and other countries, some people have dubbed subclade K a "super flu."

While other diseases like cancer and respiratory infections are significant, CVD consistently remains the leading cause of mortality worldwide, driven by factors like unhealthy diets, inactivity, tobacco, and air pollution.
