CBS News Rates of pertussis, also known as whooping cough, are surging in Texas, Florida, California, Oregon, and other states and localities across the country.
The outbreaks are fueled by falling vaccination rates, fading immunity, and delays in public health tracking systems, according to interviews with state and federal health officials. Babies too young to be fully vaccinated are most at risk.
“Pertussis cases increase in a cyclical fashion driven by waning immunity, but the size of the outbreak and the potential for severe outcomes in children who cannot be vaccinated can be mitigated by high coverage and good communication to folks at risk,” said Dr. Demetre Daskalakis, a former head of the Centers for Disease Control and Prevention’s immunization program, who resigned in August.
