Stay Alert: Recognize Key Symptoms as Flu Season Begins

A new flu strain is making headlines as it spreads rapidly across the United States. This highly contagious variant, known as subclade K of influenza A H3N2, has raised concerns among health officials. With flu season underway, recognizing key symptoms is essential for safeguarding health.

Flu Season Overview

The CDC’s latest Influenza Surveillance Report, released on December 30, indicates that 32 states are experiencing “high” or “very high” levels of flu activity. Notably, there has been a 6% increase in cases of respiratory illnesses reported by healthcare providers.

What is Subclade K?

This new strain, referred to as the “super flu,” is a mutation of the previously known influenza A. While initial data does not suggest that subclade K leads to more severe illnesses than its predecessors, it is still considered a significant development by the World Health Organization.

The CDC emphasizes the importance of getting vaccinated against flu, especially for vulnerable groups such as children and pregnant women.

Common Symptoms of Influenza

Recognizing the symptoms of the flu is crucial. According to the CDC, key flu symptoms include:

• Fever
• Cough
• Sore throat
• Runny or stuffy nose
• Muscle or body aches
• Headaches
• Fatigue
• Vomiting and diarrhea (more common in children)

When to Seek Medical Attention

It’s important to be vigilant about symptoms that may require immediate medical care. The CDC advises seeking help if any of the following occur:

• Fast or troubled breathing
• Persistent pain or pressure in the chest or abdomen
• Bluish lips or face in children
• Persistent dizziness or confusion
• Signs of dehydration
• Fever or cough that worsens after initial improvement
• Fever of 104°F (40°C) unresponsive to medication
• Fever in infants younger than 12 weeks
• Worsening of chronic health conditions

Flu vs. Common Cold

Understanding the difference between the flu and a common cold is essential. While both are respiratory illnesses, they are caused by different viruses. The flu is due to influenza viruses, whereas colds can stem from various other viruses like rhinoviruses and parainfluenza.

Flu symptoms tend to be more severe than those of a cold. Typical cold symptoms include a runny or stuffy nose and milder respiratory issues, without the serious health risks often associated with influenza.

Conclusion

As flu season progresses, remaining informed about symptoms and vaccinations is vital. Protect yourself and others by staying alert for key influenza symptoms and seeking medical attention when necessary.
