NEW ULM — As cold weather and another holiday season approaches, include more indoor activities allow viruses to pass from person to person more easily.

Pertussis, also known as Whooping Cough, is on the rise in Minnesota, according to Brown County Public Health Director Jaimee Brand.

The number of reported cases this year in Minnesota — 2,814 — is the highest number of reported cases since 2012.

Cases are beginning to show up in rural counties. There is one reported case in Brown, Watonwan and Cottonwood Counties as of Thursday, Dec. 19, according to the Minnesota Department of Health. There are two pertussis cases in Lyon County, seven in Blue Earth County, eight in Nicollet and Sibley Counties, and 18 in McLeod County.

“Pertussis is affecting people of all ages with a particular impact on children, adolescents, and young adults with the median age of those being affected being 14 years of age,” said Brand.

Infants are at the highest risk for severe illness and complications. Pertussis signs and symptoms include but are not limited to runny/stuffy nose, cough, fever, sneezing, and watery eyes.

“It is important to be seen by your healthcare provider if having a persistent or worsening cough lasting longer than seven days,” Brand said.

Two vaccines help protect against pertussis. One is for adolescents and adults. The other vaccine is for children less than age seven. Vaccine protection wanes over time, so it is important to remain up to date on vaccines that contain pertussis, such as Tdap.

“If you are feeling ill, it’s important to stay home and away from others until your symptoms get better and you are fever free for 24 hours. This guidance is true for the influenza-like illnesses and COVID-19. It’s not too late to get vaccinated. There is vaccine to protect you from pertussis, COVID-19, influenza and respiratory syncytial virus (RSV),” said Brand.

She urged the public to protect themselves by washing hands often, staying home when feeling sick, staying up to date on vaccines, taking steps for cleaner air at home and seeking medical advice when needed.

Brand said vaccine appointments and more information can be received by calling Brown County Public Health at 507-233-6820.
