RUTHERFORD COUNTY, Tenn. (WGNS) - Flu activity has surged sharply in Rutherford County as Tennessee reaches the highest level of influenza spread reported by the Centers for Disease Control and Prevention.

According to the CDC’s Weekly Influenza Surveillance Report, Tennessee was classified at Level 13 — the agency’s highest designation — for the week ending December 27, 2025. This places the state among a small group nationwide experiencing “very high” flu activity, signaling widespread and intense transmission.

Health officials note that Rutherford County has followed the same rapid escalation pattern seen statewide. Just weeks earlier, flu activity across Middle Tennessee, including Rutherford County, remained low to moderate. By mid-December, cases rose quickly, coinciding with increased travel, holiday gatherings, and colder weather conditions that favor the spread of respiratory illnesses.

CDC surveillance data shows that flu activity began climbing during the week of Thanksgiving, with a significant spike occurring between December 14 and December 20. By the final week of December, Tennessee advanced from moderate activity to the CDC’s highest alert level in less than a month.

Earlier in the season, Tennessee — along with most of the country — reported minimal flu spread through late November and early December. The sudden jump underscores how quickly influenza can intensify during peak winter months.

Local healthcare providers in Rutherford County are reporting increased patient volumes related to flu-like symptoms, and residents are being urged to take preventive measures. The CDC continues to recommend annual flu vaccination, frequent handwashing, staying home when sick, and seeking medical care if symptoms become severe or persistent.

While influenza remains the primary concern locally, the CDC also continues to monitor other respiratory illnesses circulating nationally. Vaccination and early prevention remain key tools in limiting strain on hospitals and reducing community spread.

Residents are encouraged to stay informed as flu season continues through the winter and into early spring.
