In pertussis, which phase is characterized by gradual recovery and improvement of symptoms?

• A. Convalescent phase
• B. Catarrhal phase
• C. Paroxysmal phase
• D. Inflammatory phase

Answer: (A)

Pertussis unfolds in stages, each with distinct patterns of symptoms. After the intense coughing fits of the paroxysmal phase, recovery begins in the convalescent phase. In this stage, symptoms gradually improve: the cough becomes less frequent and severe, energy returns, and overall health steadily improves over weeks. The earlier catarrhal phase shows mild, cold-like symptoms, and the inflammatory phase isn’t a standard stage used to describe pertussis progression. So the phase where recovery is gradual is the convalescent phase.
