Overview
Whooping cough (pertussis) and measles are spreading in Minnesota at rates not seen in several years. This is particularly concerning for young children, the elderly, and people with weakened immune systems, as these groups are most at risk for severe illness or complications.
Decreasing vaccination rates are likely contributing to the increase in infections, according to doctors.
Current Situation in Minnesota
In 2024, Minnesota has seen a significant rise in whooping cough and measles cases. Hospitals are on high alert due to this surge in infections.
Whooping Cough in Schools
Whooping cough has affected 826 people in Minnesota so far this year, marking the highest number of cases since 2016. Many of the affected individuals are school-aged children, with outbreaks reported in Minnetonka and Rochester schools.
The University of Minnesota has also seen a small rise in cases, though fewer than ten have been confirmed. The university plans to inform students about symptoms and precautions, as many are unfamiliar with whooping cough.
Why Pertussis Is a Concern
Whooping cough symptoms, especially the characteristic persistent cough, can last for months. Doctors are especially worried when younger patients show symptoms, as pertussis can be dangerous or even fatal in children.
“Pediatricians are very aware of this,” said Dr. Liz Placzek, a pediatrician at Children’s Minnesota. “We are being extra cautious and closely monitoring patients for possible cases.”
Measles: A Growing Concern
While there have been only 52 confirmed measles cases in Minnesota this year, the virus is highly contagious and can cause severe complications. About one in four measles patients may require hospitalization.
The Role of Vaccination
Vaccines are a key defense against both whooping cough and measles. However, vaccination rates in Minnesota have declined, particularly since the COVID-19 pandemic. According to the Minnesota Department of Health, only 77% of children born in 2021 are up to date on their whooping cough vaccinations, and 82% on their measles vaccinations—both significantly lower than a decade ago.
Vaccine Hesitancy and Public Awareness
Some doctors are seeing signs of vaccine hesitancy. Dr. Eric Barth of Alina Health mentioned that parents may not realize these illnesses are still a threat because vaccines have been so effective in the past.
“We’re victims of our own success,” Dr. Barth said. “Parents don’t realize these diseases still exist.”
Almost all measles cases in Minnesota have occurred in unvaccinated individuals. While the measles vaccine offers lifelong immunity, the whooping cough vaccine requires a booster every ten years, so even vaccinated individuals can occasionally become ill.
Conclusion
The rise in whooping cough and measles cases highlights the importance of vaccination. Doctors urge parents to ensure their children are up to date on immunizations to protect themselves and their communities.
