(St. Paul, MN) — State health officials are urging Minnesotans to make sure they are vaccinated against whooping cough. The Minnesota Department of Health says just over a thousand cases have now been reported throughout the state, compared to 61 cases during the same period last year. Vaccinations for the illness need to be updated every ten years to help decrease the severity of symptoms and the length of time it lingers. The Department of Health says whooping cough can lead to pneumonia if it is left untreated.
