Florida FLU REVIEW

Season: 2019-20 Week 12: 3/15/20-3/21/20

 Geographic Spread:
Regional

 Predominate Strain:
A 2009 (H1N1)

 ILI Activity Trend:
Decreasing

Week 12 influenza & influenza-like illness (ILI) activity summary:

Statewide, the percentage of respiratory specimens testing positive for influenza 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. Activity in week 12 was similar to an average of the past three influenza seasons for this time.

Of note, some of the figures in this report that previously displayed chief complaints of ILI were updated to display discharge diagnoses of influenza or flu to better reflect influenza activity trends in Florida.

Eight outbreaks were reported, down from eleven outbreaks in the previous week. Of the eight outbreaks reported, two were influenza-associated and six were ILI.

One new influenza-associated pediatric death was reported. Thirteen influenza-associated pediatric deaths have been reported so far this season; the majority these deaths were children who were not vaccinated for the 2019-20 season.

Influenza A 2009 (H1N1) remained the predominant strain.

The Centers for Disease Control and Prevention (CDC) continues to recommend vaccination as long as influenza viruses are circulating. Annual vaccination is especially important for people at higher risk for complications (children, adults ≥65 years, pregnant women, and people with underlying medical conditions).

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).

Your flu shot is the first and most important step to fight the flu.To locate a vaccine near you, visit: VaccineFinder.org
