Highlights

  • Masking reduces cases of pertussis among patients and health care workers.

  • Masking reduces respiratory disease transmission outside of COVID-19.

  • Waning immunity could be contributing factor to acquiring pertussis.

  • The majority of patients with known exposure to pertussis occurred at school.

  • The majority of patients who acquired pertussis were symptomatic when tested.
