South Dakota Reports First Flu Deaths of 2025-2026 Season

Northeast Radio SD News – South Dakota - State health officials have confirmed the first two influenza-related deaths of the 2025-2026 season.

According to the South Dakota Department of Health (DOH), both individuals were residents of Minnehaha County and were in the 65-and-older age group. The announcement comes as the state enters what is historically the virus’s most active period.

“Influenza can be a very serious illness,” said Dr. Joshua Clayton, State Epidemiologist. “Taking preventative measures like regularly washing hands, covering your cough, and getting vaccinated will protect you and your family.”

Statewide Activity on the Rise

As of December 31, 2025, the DOH reports that influenza activity is increasing statewide. Current data shows 2,824 lab-confirmed cases and 154 hospitalizations to date. While the two deaths are the first of this season, Clayton noted that South Dakota typically averages approximately 40 flu-related deaths per year.

The 2025-2026 season is currently trending toward a February peak, consistent with the eight-year state average. Health officials are particularly concerned for high-risk groups, including:

·        Adults over age 65

·        Children younger than five years old

·        Pregnant women

·        Individuals with chronic medical conditions

Symptoms and Prevention

Influenza is a respiratory virus spread through droplets when an infected person talks, coughs, or sneezes. Common symptoms include fever, cough, sore throat, headache, fatigue, and muscle aches.

To slow the spread, the DOH recommends several key actions:

·        Vaccination: Yearly shots are recommended for everyone age six months and older.

·        Hygiene: Wash hands often with soap and water and avoid touching your eyes, nose, or mouth.

·        Distancing: Avoid close contact with those who are sick and stay home if you develop symptoms yourself.

“At the heart of the Department of Health’s mission is a simple yet profound goal: to protect and improve the health of all South Dakotans,” the department stated in a release, urging residents to utilize local clinics and pharmacies for vaccination.
