Marathon County Health Department confirms community spread of Pertussis

The Marathon County Health Department has identified several cases of pertussis, also known as whooping cough, in the county, consistent with the statewide and national increase reported by the CDC. Pertussis is a highly contagious bacterial disease that can affect people of all ages. However, it can be severe, especially for pregnant people, babies, and those with weakened immune systems.

Symptoms start like a cold and progress to severe coughing fits with a distinctive 'whooping' sound, sometimes leading to vomiting. Symptoms typically appear 710 days after exposure but can occur as early as five days and as late as 21 days after exposure.

If you have symptoms or suspect exposure, stay home from school, work, and other activities and consult a medical provider. The earlier someone starts treatment the better. Individuals with pertussis should be treated with antibiotics by their medical provider. Pertussis can cause serious complications in babies, such as pneumonia and seizures, and can be fatal.

Vaccination is the best prevention. The CDC recommends the pertussis vaccine for all babies, children, preteens, pregnant people, and adults who haven't received it. To check if you or your loved ones are up to date on your vaccinations that protect against pertussis, contact your medical provider or check the Wisconsin Immunization Registry at https://www.dhfswir.org/.

The CDC reports that pertussis cases have tripled nationwide in 2024 compared to the same period in 2023, returning to pre-pandemic levels seen in 2019.
