Whooping Cough Reaches Highest Levels in a Decade in the US

MILWAUKEE -- Whooping cough (pertussis) has reached its highest level in a decade for this time of year, according to U.S. health officials.

The Centers for Disease Control and Prevention (CDC) reported 18,506 cases so far, the highest count since 2014, when cases exceeded 21,800 at this time. The peak in whooping cough cases every three to five years is anticipated, indicating a return to pre-coronavirus pandemic levels.

Concerns are rising among state health officials, particularly in Wisconsin, which has recorded about 1,000 cases this year compared to only 51 last year. A national decline in kindergarten vaccination rates and an all-time high in vaccine exemptions have also been noted by the CDC. Currently, about 86% of kindergarteners in Wisconsin have received the whooping cough vaccine, versus over 92% nationally.

Initial symptoms of whooping cough resemble a cold, progressing to a prolonged cough, often referred to as the "100-day cough." Antibiotics are the standard treatment. Vaccination, a routine part of childhood immunizations since the 1950s, is critical for protection, especially for infants and young children who face serious risks from the disease.

Public health officials report that this year's outbreaks are increasingly affecting older children and teens. Most cases in Pennsylvania's outbreaks are in middle and high school settings, while Douglas County, Nebraska, has reported significant cases among school-age children.

Early testing and antibiotic treatment are essential, as highlighted by pediatric infectious disease specialists. As emphasized, “Pertussis is worth preventing,” thanks to safe and effective vaccines available.
