Hamilton County Disputes Wastewater Scan Showing 1,000 Norovirus and Rotavirus Cases

Summary
Hamilton County health officials said local surveillance shows low to moderate norovirus and rotavirus activity, contradicting a wastewater dashboard that flagged medium norovirus and high rotavirus levels in the Chattanooga area.
More than 1,000 cases were reported from August 2025 through last month, according to CDC data cited in the report, but the department said its epidemiologists rely on multiple sources rather than wastewater readings alone.
Dr. Stephen Miller said both viruses can spread quickly in places such as summer camps, restaurants and long hiking trails, with symptoms often hitting within six to 12 hours and clearing in about three days.
Older adults, immunocompromised people and those with chronic illnesses face higher risk, and the department urged hand washing, hydration and rest as summer travel and gatherings continue.
