2025 - 2026 Licking County Influenza (Flu) Report

Influenza is a respiratory virus that affects the nose, throat, and sometimes the lungs by presenting symptoms such as fever, cough, sore throat, runny/stuffy nose, muscles aches, and fatigue. Flu cases start to increase when outside temperatures decline, and people are spending more time indoors (close contact). The flu season runs from October to May, but LCHD continues surveillance year-round to detect any unusual trends. It is important to prevent yourself from getting the flu by getting vaccinated to keep yourself and others protected. 

PLEASE NOTE: For seasonal numbers, these are case totals by the flu season. The flu season starts at week 40 of the year and goes until week 39 of the following year. The flu season then resets at week 40 of each year.
