CHATTANOOGA, Tenn — Tennessee health officials say flu activity is rising sharply in around Chattanooga, with counties surrounding Hamilton showing some of the highest rates in the state.

Marion, Grundy, Sequatchie, Bradley, Meigs, Rhea, Bledsoe, McMinn and Polk counties are currently the only areas in Tennessee rated “very high” for influenza activity by the Centers for Disease Control and Prevention.

These counties have flu positivity rates greater than 10 percent. By comparison, the statewide average is 6.5 percent, and Hamilton County itself is at 6.9 percent.

State and federal health experts say the surge comes as influenza A(H3N2) continues to circulate widely. The CDC reports at least 11 million flu illnesses, 120,000 hospitalizations, and 5,000 deaths nationwide so far this season. One pediatric death was reported this week in Tennessee, bringing the season total to nine nationwide.

Georgia officials are also reporting higher-than-average flu activity, signaling that the region is experiencing a particularly active season. Health authorities encourage residents six months and older to get vaccinated if they have not already and to take precautions such as frequent handwashing and staying home when sick.

Flu activity is expected to remain elevated in Tennessee and across the U.S. for several more weeks, according to the CDC. Local hospitals and clinics are urging families to monitor symptoms and seek care early, especially for children, older adults, and those with chronic health conditions.
