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

In week 15, ILI activity continued to decrease and was similar to levels observed at this time in past seasons. Activity has peaked for the season; however, the influenza season is not over yet and outbreaks continue to be regularly reported.

The timing of peak activity this season varied across regions, ranging from as early as week 52 (ending December 29, 2018) to as late as week 9 (ending March 2, 2019). For more information on regional trends, see page 8.

Most counties continued to report mild influenza activity in week 15. In week 15, five counties reported moderate influenza activity.

In week 15, six respiratory outbreaks were reported (up from four outbreaks in week 14). A total of 223 respiratory outbreaks have been reported so far this season.

No new influenza-associated pediatric deaths were reported in week 15. 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.

On March 28, 2019, the Centers for Disease Control and Prevention (CDC) released an official health advisory reminding clinicians to have high suspicion for influenza and to prescribe antiviral treatment to high-risk patients with suspected influenza. Antiviral treatment should be started as soon as possible after illness onset and should not wait for laboratory confirmation. Early treatment should not be delayed for hospitalized and high-risk patients, especially those aged 65 years and older. For more information, please visit: emergency.cdc.gov/han/han00419.asp.

It’s not too late to get your flu vaccine. CDC recommends influenza vaccination as long as flu 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)
