Week 14 influenza & influenza-like illness (ILI) activity summary:

Overall, influenza activity is low statewide.

The percent of influenza-positive laboratory results continued to decrease.

Likewise, the percent of emergency department and urgent care center visits with discharge diagnoses that include influenza or flu decreased in recent weeks.

No outbreaks were reported. Six outbreaks were reported during the previous week.

No new influenza-associated pediatric deaths were reported. Thirteen influenza-associated pediatric deaths have been reported so far this season; the majority of these deaths were in children who were not vaccinated for the 2019-20 season.

Influenza A 2009 (H1N1) remained the predominant strain.

In addition to getting vaccinated, the Florida Department of Health recommends you take everyday precautions to prevent the spread of influenza:

  • Wash your hands often with soap and water (if soap is not available, use an alcohol-based sanitizer).
  • Avoid touching your eyes, nose, and mouth.
  • If you do get sick with influenza, stay home until fever-free for at least 24 hours (without the use of fever-reducing medication).

The COVID-19 pandemic is affecting health care seeking behavior, which may be impacting the ILI and influenza activity trends shown in this report. An overall reduction in the number of emergency department and urgent care center visits has been observed in recent weeks, along with changes in the reasons for seeking care at these facilities.
