Colorado Whooping Cough Cases Rise Amidst Declining Vaccination Rates
Colorado is experiencing a significant resurgence of whooping cough, or pertussis, with over 930 cases reported in 2024 and 2025, a sharp increase after reaching pandemic-era lows. State health officials attribute this rise to declining school vaccination rates and waning immunity, as a notable portion of reported cases involve vaccinated individuals. While vaccination remains the most effective prevention, breakthrough infections can occur, and health experts emphasize the importance of booster doses to maintain protection against the highly contagious disease.
