The Michigan Department of Health and Human Services (MDHHS) has raised concerns about a rise in pertussis cases, commonly referred to as whooping cough, and is urging residents to update their vaccinations. The state has reported 830 confirmed or probable cases this year by October 28, surpassing last year's numbers.

From 2017 to 2019, Michigan averaged 596 pertussis cases annually. The current figures reflect a return to pre-pandemic patterns of higher national case numbers.

Pertussis symptoms initially resemble a common cold and may appear five to ten days after exposure. In some instances, infants and young children may experience breathing pauses known as apnea instead of coughing. Severe coughing fits can develop later.

Pertussis is prevalent in the United States and poses serious health risks for individuals of all ages, particularly infants. In 2024, the median age for pertussis cases is 13 years, with 75% occurring in individuals under 18.

Dr. Natasha Bagdasarian, chief medical executive at MDHHS, stated: "Vaccinations continue to be our top line of defense against the spread of pertussis." She emphasized that declining immunization rates are contributing to an increase in pertussis and other vaccine-preventable diseases across the state. "We encourage all Michiganders to stay up to date with their immunization schedule," she added.

The Centers for Disease Control and Prevention (CDC) advises that infants, children, adolescents, pregnant individuals, and adults who have not received a dose should get vaccinated against pertussis.

Michigan's childhood immunization rates are decreasing, putting more children at risk for severe pertussis illness. Currently, 82.9% of children receive their first Diphtheria, Tetanus, Pertussis (DTaP) vaccine dose by three months old; however, only 65.6% complete all four recommended doses by 19 months old.
