US Whooping Cough Cases Surge by Over 340%, CDC Reports

The dramatic rise in infections is linked to missed vaccinations and waning immunity post-pandemic.

The Centers for Disease Control and Prevention had preliminarily documented more than 17,600 whooping cough infections in the U.S. as of Oct. 5, 2024—more than four times the nearly 4,000 infections recorded at this time in 2023.
