The U.S. has recorded over 32,000 whooping cough cases this year, compared with around 5,100 as of mid-December last year. Infants are most vulnerable to the bacterial infection.

Summary

Whooping cough cases in the U.S. have surged to over 32,000 in 2024, marking the highest annual total in a decade and a six-fold increase from 2023.

Experts attribute the rise to waning vaccine immunity, declining vaccination rates, and improved diagnostic testing.

Infants are most vulnerable, with severe cases requiring intensive care, and unvaccinated children are at highest risk.

Vaccination rates have declined despite high levels. Health officials urge vaccination to combat the resurgence, emphasizing the disease’s potentially fatal complications.
