Montana Reports Second Flu Death, Cases and Hospitalizations Rising

Montana recorded a second influenza related death this season, confirmed by RiverStone Health, as state level case counts and hospitalizations trended upward compared with the same point last year. The most recent publicly available state data through December 19 showed more than 1,200 influenza cases statewide, with a striking concentration of illness and a large share of hospitalizations reported in Yellowstone County.

Health authorities reported that hospitalizations this season were skewing toward older adults, raising concern for counties with sizable senior populations including Lewis and Clark County. Officials advised vaccination as the primary preventive measure, and they urged residents to practice routine precautions such as hand hygiene and staying home while ill. For people at higher risk of severe influenza complications, clinicians were encouraged to consider antiviral treatment when appropriate.

Reporting delays were noted, and state level numbers reflected the situation through December 19, 2025. That caveat means additional cases and hospital stays that occurred after that date may not yet be reflected in the totals. Public health providers emphasized monitoring local clinic capacity and the availability of antiviral medications for patients with risk factors such as chronic medical conditions and advanced age.

For Lewis and Clark County residents the immediate implications were practical. Vaccination remained the most accessible protection as clinics and pharmacies continued offering flu shots. Older adults and people with underlying health conditions faced higher chances of hospitalization if infected, making timely vaccination and prompt care important. Staying home while ill was advised to limit transmission in workplaces, schools, and care facilities.

As influenza activity rose statewide, local health systems and providers were asked to remain vigilant for worsening illness and to prioritize testing and treatment for those most vulnerable. Residents concerned about symptoms were told to contact their health care provider for guidance on testing and whether antiviral medication might be appropriate.
