Whooping Cough Outbreaks on the Rise Amid Declining Vaccination Rates

A growing number of US states are experiencing outbreaks of whooping cough, or pertussis, as vaccination rates among children continue to decline. In Louisiana, 110 pertussis cases have been confirmed in just six months, with two deaths reported. Nationally, over 35,000 cases were reported last year, the highest in over a decade.

Experts attribute the rise in outbreaks to declining vaccination rates over the past five years. When vaccine efficacy is questioned or doubted, it can lead to a decrease in overall vaccine confidence and a ripple effect on all vaccines.

“Pertussis vaccination is essential,” said Jennifer Avegno, director of the New Orleans Health Department. “When you cast aspersions or doubt about the safety and efficacy of one vaccine, I think it really has a ripple effect for all vaccines.”

The Centers for Disease Control and Prevention (CDC) reports that 6,600 cases of pertussis have already been confirmed in 2025, nearly four times the number seen at this point last year. Experts urge parents to prioritize their children’s vaccination schedules to prevent further outbreaks.
