The CDC released numbers for pertussis cases up until April 26. There have been 9,034 cases reported in 2025 compared to 4,698 by this date in 2024. In early April, a Weston elementary school warned parents that one case of whooping cough had been confirmed there. The best way to prevent whooping cough is to get vaccinated, the CDC says. In 2024, the Food and Drug Administration met to discuss the need for more robust and longer-lasting versions of the whooping cough vaccine.
