FSU Expert Shares Insights on Upcoming Flu Season Challenges

As influenza season approaches, typically spanning from October through May, health experts are urging vigilance as flu cases begin to rise. Dr. George Rust, director of the Center for Medicine and Public Health at Florida State University, emphasizes the importance of preparation, especially as the Centers for Disease Control and Prevention (CDC) reported that flu cases reached their highest levels in 15 years in February 2025.

The flu virus spreads primarily through respiratory droplets when an infected person speaks, sneezes, or coughs, highlighting the need for awareness and preventive measures. The CDC identifies common flu symptoms, including fever, chills, cough, sore throat, runny or stuffy nose, headache, fatigue, muscle aches, and in some cases, gastrointestinal issues like nausea and diarrhea.

Flu Season Timing and Vaccination Recommendations

Dr. Rust notes that Florida’s flu season tends to peak later than in other regions, with most cases occurring between mid-December and mid-February. He advises individuals to receive their flu shot in October or November for optimal protection ahead of holiday gatherings. “It takes two weeks for the flu shot to provide full protection, but that protection can wane after several months,” says Dr. Rust.

The CDC has observed a concerning trend of declining flu vaccination rates among both adults and children, making it crucial for communities to prioritize immunization. Dr. Rust encourages everyone to consider getting vaccinated before the onset of the holiday season to minimize the risk of infection during family gatherings.

Recognizing Symptoms and When to Seek Medical Attention

Determining whether an illness is a cold or the flu can be challenging. Dr. Rust explains that symptoms for a cold often include sneezing, a runny nose, and mild fever, while influenza typically results in more severe symptoms, such as high fever, significant fatigue, and body aches.

For those unsure about their symptoms, Dr. Rust advises staying home if feeling unwell, to prevent spreading illness to others. “If symptoms worsen or if you have underlying health conditions that increase your vulnerability, it is wise to consult a physician,” he states. Rapid flu tests are available at many healthcare facilities and can help confirm a diagnosis, allowing for timely treatment if necessary.

The doctor also highlights the importance of recognizing warning signs that indicate a need for immediate medical assistance. These include difficulty breathing, chest pain, dizziness, or persistent fever returning after initial improvement.

In addition to vaccination, Dr. Rust suggests adopting healthy daily habits to strengthen the immune system. Regular exercise, a balanced diet, adequate sleep, and effective stress management techniques can significantly reduce the likelihood of contracting the flu.

He emphasizes the importance of hand hygiene, particularly in crowded environments during the flu season. “Carrying hand sanitizer and wearing a well-fitted mask, such as an N-95, can provide additional protection, especially for those with compromised immune systems,” Dr. Rust advises.
