ILI Activity Trend:
Influenza & influenza-like illness (ILI) activity summary:
In week 49, activity decreased, but remained above levels observed at this time in previous seasons.
Influenza and ILI activity remained particularly elevated in children for this time in the season.
In week 49, two influenza-associated pediatric deaths were reported, both in children who were not yet vaccinated for the 2019-20 influenza season. These mark the first deaths reported in Florida for the 2019-20 season. For more information, see page 10.
Get your flu shot now; it’s not too late! Annual vaccination is the best way to protect yourself and your loved ones from influenza and its potentially severe complications. Children, especially those <2 years and those with certain underlying medical conditions, are at higher risk for severe complications from influenza infection. Vaccination has been shown to reduce a child’s likelihood of dying from influenza by 60%.
Influenza vaccines are designed to protect against the three or four strains experts believe will be most common during the season.
Consistent with the national trend, influenza B Victoria lineage remains the most common subtype identified at the Bureau of Public Health Laboratories so far this season. An influenza B Victoria lineage strain is included in the 2019-20 quadrivalent and trivalent vaccine options.
In week 49, four outbreaks were reported, down from seven outbreaks reported during the previous week. Of the four outbreaks reported, two were influenza-associated and two were ILI.
Most county health departments reported mild activity.
The Centers for Disease Control and Prevention recommends antiviral treatment be initiated as soon as possible for people with confirmed or suspected influenza who are at higher risk for complications (children <2 years, adults ≥65 years, pregnant women, and people with underlying medical conditions). Treatment should be administered within 48 hours of illness onset. For more information, contact your health care provider.
