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

In week 49, influenza and ILI activity increased statewide. It is expected that influenza and ILI activity will increase further over the coming weeks as the season progresses.

Eight new outbreaks of influenza or ILI were reported: two influenza A unspecified and six ILI. A total of 37 influenza or ILI outbreaks have been reported so far this season. For a complete list of outbreaks reported so far this season, see page 14.

No new influenza-associated pediatric deaths were reported in week 49. Two influenza-associated pediatric deaths have been reported in Florida so far during the 2018-19 influenza season. Both deaths occurred in unvaccinated children. Influenza vaccination can reduce a child’s likelihood of dying from influenza by up to 60%. For more information, see page 10.

Consistent with the national trend, influenza A 2009 (H1N1) has been the most commonly identified influenza subtype at the Bureau of Public Health Laboratories so far this season. Influenza A (H3) and influenza B Yamagata lineage viruses have also been identified as co-circulating in Florida. Influenza vaccines are designed to protect against all of these viruses.

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. Getting vaccinated for influenza can:

  • Keep you from getting sick with flu
  • Reduce your risk of flu-associated hospitalization
  • Be life-saving in children
  • Help protect women during and after pregnancy and can offer protection from flu to the baby for several months after birth

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).
