The clinical term "whooping cough" is so named because the term "hundred days" refers to the duration of the cough, symbolizing that the cough lasts a long time, the disease course is prolonged, and it tends to recur. It doesn’t necessarily mean that one will cough for exactly one hundred days. One should relax and have the correct understanding. For treating such diseases, sensitive antibiotics should be used promptly, along with symptomatic treatment. Blood tests such as a complete blood count and C-reactive protein should be conducted, along with chest X-ray, and sputum pathogen culture for definitive diagnosis, to ensure early detection and treatment.
