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

In week 6, ILI activity increased statewide and was above peak activity levels observed during the 2016-17 and 2015-16 seasons. Increases were observed in all regions, including the southeast (see page 8). Heightened influenza activity is expected for several more weeks.

While most counties reported mild influenza activity for week 6, 22 counties reported moderate influenza activity (up from 16 counties in week 5). One county reported elevated influenza activity.

A notable uptick in the number of influenza and ILI outbreaks was observed. Twenty-seven outbreaks were reported in week 6 (19 with laboratory evidence of influenza and eight ILI). A total of 115 influenza or ILI outbreaks have been reported so far this season (see page 14).

One new influenza-associated pediatric death was reported in week 6 in an unvaccinated child with no known underlying medical conditions. Influenza vaccination can be life-saving in children. For more information, see page 10.

In recent weeks, an increase in the number of influenza-positive specimens subtyped as influenza A (H3) at the Bureau of Public Health Laboratories in Florida has been observed. Both influenza A 2009 (H1N1) and influenza A (H3) viruses have co-circulated throughout the season in Florida, with influenza A 2009 (H1N1) remaining the most common overall. Mid-season changes in predominantly circulating strain have been observed in past seasons in Florida. This trend will continue to be monitored closely.

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. These vaccines are designed to protect against both influenza A 2009 (H1N1) and influenza A (H3) viruses, as well as one or two influenza B viruses.

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)
