New Flu Variant Spreading Rapidly Across U.S., Experts Warn of Severe Symptoms

Chicago, IL – A concerning new flu variant, known as subclade K, is rapidly spreading across the United States, prompting warnings from health officials as holiday gatherings approach. Doctors are reporting a surge in cases with unusually severe symptoms, particularly among children.

“We have to be careful,” stated Dr. Juanita Mora, a national spokesperson for the American Lung Association, in an interview. “Just today I’ve got 15 calls with flu positive patients.”

The new strain is causing high fevers (104-105°F) that are difficult to control with medication. Other symptoms include a persistent, phlegmy cough, vomiting, diarrhea, and significant joint and muscle aches.

Dr. Suchitra Rao, an infectious disease specialist at Children’s Hospital Colorado, said, “I don’t think I ever remember seeing it this severe, this soon. Our emergency department is full of kids coming in with the flu.”

While Illinois cases currently remain minimal compared to other Midwest states, data from the Illinois Department of Public Health show a rise in hospital admissions for the flu.

Warning Signs and When to Seek Medical Attention:

Dr. Mora emphasized the importance of recognizing warning signs that require immediate medical attention:

  • High fevers that don’t break
  • Shortness of breath, wheezing, or difficulty breathing
  • Dehydration

The CDC warns that influenza can spread one day before symptoms even appear.

Vaccine Effectiveness and Prevention:

While current flu vaccines are expected to provide some protection against serious illness, they were not specifically designed to target the subclade K variant. As a result, health officials anticipate the vaccine might be less effective.

Despite this, health officials urge everyone to get vaccinated. The Illinois Department of Public Health said the vaccine is expected to still offer some protection, though she noted the new strain is still believed to be more contagious.

Experts also stress the importance of preventative measures:

  • Frequent handwashing
  • Wearing a mask when sick
  • Avoiding close contact with vulnerable individuals, such as newborns and the elderly

A Challenging Flu Season Ahead?

Flu seasons typically peak around February, making it difficult to predict the full impact of the new variant. However, with cases rising and the potential for more severe symptoms, health officials are urging the public to take precautions to protect themselves and others.
