The manifestations of the recovery phase of whooping cough, also known as pertussis, include a gradual reduction and alleviation of symptoms. The frequency and number of paroxysmal, spasm-like coughing attacks will progressively decrease and may even disappear completely. It's important to adjust your mindset and correctly understand the situation. Regarding diet during the recovery period, it's also advisable to avoid overly greasy, sweet, or spicy foods and consume more light, soft, and easily digestible foods. Medication should be chosen according to the treatment course, and regardless of whether the symptoms have completely alleviated, regular follow-up checks should be conducted after one treatment course.
