Flu cases are rising earlier than usual in Florida this season, with emergency room visits for the flu also increasing. As of Nov. 9, Florida carried a Walgreens flu score of 4.94, well above the national average of 3.03.
Why it matters
Respiratory viruses spread more easily as temperatures drop and people spend more time indoors, and an early season leaves residents exposed for longer. Health officials are urging vaccination now, before peak activity arrives.
The Walgreens Flu Index, which scores state flu activity from 0 to 10 using pharmacy test positives, prescriptions, and cold-and-flu medication sales, puts Florida at 4.94 against a national average of 3.03. The index does not indicate how Florida's current levels compare with earlier seasons.
The players
Centers for Disease Control and Prevention (CDC)
The CDC is the U.S. federal public health agency that issues national vaccination recommendations, including the guidance that everyone aged six months and older get a flu shot by the end of October.
Walgreens
Walgreens is a national pharmacy chain whose Flu Index aggregates positive flu tests, prescriptions, and cold-and-flu medication sales to score state-level flu activity.
The details
More people are getting influenza earlier in the season than in previous years, and emergency room visits for the flu have increased in Florida. The CDC recommends everyone get a flu vaccine by the end of October, and vaccines are available at pharmacies, healthcare provider offices, grocery store pharmacies, and county health departments.
Timeline
End of October: CDC recommended deadline for flu vaccination
October through March: Typical flu season window
January or February: Flu activity usually peaks
Nov. 9: Florida Walgreens flu score of 4.94 reported
Seasonal Patterns
The CDC's annual recommendation that everyone six months and older get a flu shot by the end of October is built around a season that typically runs from October through March and peaks in January or February. Florida's early rise this year compresses that timeline, leaving less margin between the recommended vaccination date and the start of transmission.
Flu vaccination provides immunity within two weeks, so getting the shot before the end of October gives your body time to respond before the early-season rise intensifies. Vaccines are available at pharmacies, doctor's offices, grocery store pharmacies, and county health departments, and everyone six months and older is recommended to get one.
The takeaway
Getting vaccinated before the end of October gives your body about two weeks to build immunity before the season's expected January-February peak, and an early Florida rise means that window matters more this year.
What happens next
Flu numbers are expected to peak in January or February, which will show whether the early-season rise in Florida continues.
