  • The clinical presentation is divided into 3 phases:
    • Catarrhal: cough and congestion with low-grade fever and coryza.
    • Whooping: characteristic cough.
    • Resolution: recovery with persistent cough.
  • Infants may not get this presentation, but may get apnea and nonspecific cough.
  • Tongue depressor can be used to elicit cough for diagnosis.
