Influenza & influenza-like illness (ILI) activity summary:

In week 11, ILI activity decreased slightly. Levels remained similar to those observed at the peak of the 2016-17 season.

Regional differences continued, with activity remaining highest in the western panhandle. For more information on regional trends, see page 8.

Most counties continued to report mild influenza activity in week 11. In week 11, nine counties reported moderate influenza activity.

In week 11, 16 outbreaks of influenza or ILI were reported (down from 19 outbreaks in week 10). Most of these outbreaks (69%) were reported in facilities serving children. A total of 200 influenza or ILI outbreaks have been reported so far this season.

No new influenza-associated pediatric deaths were reported in week 11. Three influenza-associated pediatric deaths have been reported so far this season, all in unvaccinated children. Influenza vaccination can be life-saving in children. For more information, see page 10.

Influenza A (H3) viruses now make up the majority of influenza A viruses subtyped at the Bureau of Public Health Laboratories this season. Both influenza A 2009 (H1N1) and influenza A (H3) viruses have co-circulated throughout the season in Florida. Mid-season changes in predominantly circulating strain have been observed in past seasons in Florida.

It’s not too late to get your flu vaccine. People who have not yet been vaccinated for the 2018-19 season should do so as soon as possible. Influenza vaccines are safe and are the best way to protect yourself and your loved ones from influenza and its potentially severe complications. The Centers for Disease Control and Prevention continues to recommend influenza vaccination now and as long as influenza viruses are circulating.

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

  • 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, stay home until fever-free for at least 24 hours (without the use of fever-reducing medication)
