Influenza cases in Montana hit a sharp rise at the start of December, with nearly 1,000 new cases and more than 50 new hospitalizations reported statewide last week.

According to the Montana Department of Health and Human Services weekly influenza report, cases and hospitalizations have rapidly increased in recent weeks and are far ahead of historical averages for this time of year.

Season to date, the department has reported 2,708 total flu cases, 120 hospitalizations and two deaths associated with flu.

Flathead County reported 73 new cases during the week ending Dec. 3.

Logan Health Medical Center officials told the Inter Lake on Dec. 9 that 11 people were hospitalized with the flu.

“We’ve seen admissions continue to increase every day for flu and RSV,” hospital officials said in a statement. “In general in our outpatient settings, we are seeing a lot of positives … for flu, RSV and Covid-19, as well.”

State data shows the current flu season in Montana starting far in advance of recent seasons, with the first cases cropping up in mid-October. Over the last five seasons, the first cases weren’t reported until early December.

Most of the current flu hospitalizations in the state are patients over 65 years old. Fewer than 10 of the hospitalizations are patients under 18.

Both of the reported flu-related deaths were in individuals over 65.

Gallatin County has seen the worst flu outbreak in the state, with 830 cases reported so far this season. Yellowstone County has reported 598 total cases.

Influenza A is the dominant influenza type circulating in Montana, according to the Montana Department of Health and Human Services. The flu vaccine is available by appointment at the Flathead County Health Department. People should call 406-751-8110 to schedule a time.

Alongside the rise in flu cases, state data shows Covid is circulating as well. Flathead County reported 47 active Covid cases as of Dec. 9, and Logan Health officials reported four Covid-19 hospitalizations.

Yellowstone County reported the highest level of new Covid cases, with 346 active cases on Dec. 9. Cascade County had 237 active cases.

Montana Department of Health and Human Services also warned that circulation of RSV is increasing in Montana, with a positivity rate near 16% last week.
