Unique Symptoms Of Flu In 2026 And How Long Infection Now Last

Flu cases are surging, and reports have shown that this year is the worst hit of all, with record breaking cases, and hospital visits are highest in the last 25 years.

Data from the Centers for Disease Control and Prevention (CDC), US, has shown that this year, the visits to doctor for fever, cough and a sore throat, which are common among flu symptoms have been highest since 1997-98 flu season. The data was published on Monday Dr Caitlin Rivers, an epidemiologist and senior scholar at Johns Hopkins Center for Health Security said, "This is definitely a banner year. It’s the worst we’ve had in at least 20 years. We’re seeing a majority of the country is experiencing very high levels of activity, and we’re still in the thick of it.”

Not just that, but this year, we have a new unique symptom added on the list. 

The fast-spreading flu is thanks to the mutated virus of influenza A or the H3n2 virus, which is called the subclade K. It is known to cause the <span>superflu</span>. Experts say this is partly because the virus has changed enough to slip past immunity built from earlier vaccinations or past illness, making outbreaks harder to control. Older adults and other high-risk groups tend to be affected most.

Many patients have described vomiting “yellow bile” as one of the standout symptoms of their flu infection. Virologists believe this may happen because the flu is suppressing appetite more than usual, leading people to vomit when their stomachs are empty.

People experiencing symptoms such as coughing, sore throat, or a runny nose have been advised to reduce contact with vulnerable groups. This includes older adults, pregnant women, and those with existing health conditions, as they face a higher risk of serious illness.

The main illness lasts about a week, cough and tiredness can linger for 1-2 weeks or longer, with full recovery taking time, especially for at-risk.

<h2>What Are The Other Symptoms Of The Superflu?</h2>

Additional flu symptoms include muscle pain, fever, weakness, extreme tiredness, and a dry cough. These symptoms often start suddenly and usually mean staying in bed to recover. Professor Stephen Griffin, a virology expert at the University of Leeds, told the Daily Mail that people vomiting yellow bile should focus on staying hydrated. “It’s important to drink plenty of water, even if you’re being sick, because some fluid will still be absorbed,” he said.

While many flu symptoms are widely recognized, some are less commonly associated with the illness. The NHS lists ten typical flu symptoms, which often appear suddenly.

Among these, three signs that people may overlook are trouble sleeping, a reduced appetite, and feeling unusually tired or drained. During the busy weeks leading up to Christmas, these symptoms can easily be dismissed as stress or exhaustion rather than flu.

Home Secretary Shabana Mahmood, as per The Independent, said that strikes within the NHS “undoubtedly” put lives at risk. Speaking to Sky News’ Sunday Morning With Trevor Phillips, she said, “We want to ensure the NHS is supported through a difficult winter and this flu outbreak we are currently seeing. It is important that everyone understands what is at stake.”

She also pointed to a difference between the position taken by resident doctors’ leadership and the views of individual doctors, noting that the situation remains sensitive as the NHS navigates one of its most demanding winter periods.
