Week 16: April 17-23, 2016

http://www.floridahealth.gov/diseases-and-conditions/influenza/_documents/2015-16/2016-w16-flu-review.pdf

Summary
State influenza and influenza-like illness (ILI) activity:
 Florida reported ?sporadic? activity to the Centers for Disease Control and Prevention (CDC)
in week 16.
 Influenza activity this season peaked between weeks 7-11. This peak in activity has
occurred later than in the past six seasons.
 Emergency department (ED) and urgent care center (UCC) visits for ILI peaked in week 9
and continues to decline in nearly all regions in Florida. These levels are similar those seen
in previous seasons at this time.
 In recent weeks, the preliminary estimated number of deaths due to pneumonia and
influenza remained elevated. The most notable increase in deaths due to pneumonia and
influenza were observed in the 55-74 age group. Deaths due to pneumonia and influenza
tend to occur later in the season as at-risk populations develop complications from influenza
infection.
 Due to a late season peak, we anticipate that we will continue to see an increase in
pneumonia and influenza-associated deaths in the next few weeks.
 In week 16, the majority of counties reported ?mild? or no influenza activity.
 No influenza-associated pediatric deaths were reported in week 16.
 Seven influenza-associated pediatric deaths have been reported so far this season.
While rare, Florida receives reports of influenza-associated pediatric deaths each
season. Annual vaccination remains the best way to protect children against the flu.
 In week 16, two outbreaks of influenza and one outbreak of ILI were reported in a St. Johns
County school, a Clay County school, and a Pinellas County nursing home, respectively.
 Influenza A 2009 (H1N1) has been the most common influenza subtype identified by the
Bureau of Public Health Laboratories (BPHL) this season. As we transition into the summer
months, it is not uncommon for the predominately circulating strain of influenza to change.

Summary
State influenza and influenza-like illness (ILI) activity:
 Florida reported ?sporadic? activity to the Centers for Disease Control and Prevention (CDC) in
week 15.
 Influenza activity this season peaked between weeks 7 and 11 (mid-February to mid-March).
This peak in activity has occurred later than in the past six seasons.
 Emergency department (ED) and urgent care center (UCC) visits for ILI continued to decrease in
nearly all regions in Florida and are similar to levels seen in previous seasons.
 In recent weeks, the preliminary estimated number of deaths due to pneumonia and influenza
remained slightly elevated. The most notable increase in deaths due to pneumonia and
influenza were observed in the ≥75 age group. Deaths due to pneumonia and influenza tend to
occur later in the season as at-risk populations develop complications from influenza infection.
 In week 15, the majority of counties reported ?mild? or no influenza activity.
 One influenza-associated pediatric deaths was reported in week 15 in Palm Beach County. The
child had underlying health conditions and influenza vaccination status is unknown.

rare, Florida receives reports of influenza-associated pediatric deaths each season. Annual
vaccination remains the best way to protect children against the flu.
 In week 15, two outbreaks of influenza A were reported in a Palm Beach County correctional
facility and a St. Lucie County elementary school.
 Influenza A 2009 (H1N1) has been the most common influenza subtype identified by the
Bureau of Public Health Laboratories (BPHL) this season. As we transition into the summer
months, it is not uncommon for the predominately circulating strain of influenza to change.
