Flu season is underway in Florida, and health officials are already reporting a notable rise in cases. The latest data from the Florida Department of Health, covering the week of September 15-21, 2024, shows an uptick in both flu-related emergency department visits and positive flu tests.

The predominant strain currently spreading is Influenza A H3. Emergency departments across the state have reported increased visits for flu-like symptoms compared to previous weeks, with Polk County already seeing a confirmed flu outbreak.

Rising Flu Activity Prompts Precautions

Flu seasons can vary in intensity and timing, and this year is shaping up to be an active one. Health experts are urging Floridians to take the rise in cases seriously and get vaccinated before the virus spreads further. According to information on the most recent week's report, the flu shot, which takes about two weeks to become fully effective, remains the most reliable way to protect against severe illness.

What Floridians Need to Know

• Flu Strain: The dominant strain is Influenza A H3.
• Flu Positivity Rate: Data from emergency departments indicate that more people are testing positive for flu this week compared to the previous three-week average.
• Outbreaks: Polk County reported one flu outbreak.

The Florida Department of Health monitors flu trends to track outbreaks, guide vaccine development, and prepare for severe cases, especially among the most vulnerable. While individual flu cases are not required to be reported in Florida, all outbreaks and pediatric flu deaths must be reported.

Health officials are strongly encouraging Floridians to get vaccinated as soon as possible. With flu activity on the rise, the window for getting ahead of the virus is closing. The flu vaccine is especially important for high-risk groups, such as children under two, seniors over 65, and individuals with underlying health conditions.

Flu vaccines are available at local pharmacies, healthcare providers, and community health clinics. To find a flu vaccine near you, visit VaccineFinder.org.

With flu cases expected to continue climbing in the coming weeks, now is the time for Floridians to protect themselves and their communities by getting vaccinated and practicing good hygiene habits, such as frequent handwashing and staying home when sick.

For those who experience flu-like symptoms, including fever, cough, or sore throat, antiviral medications may be recommended, especially if treatment begins within 48 hours of symptom onset.
