The whooping cough we refer to clinically is a type of respiratory infectious disease. The term "hundred days" relates to the duration of the disease, which is relatively long, sometimes approaching one hundred days, hence the name whooping cough. However, it does not necessarily mean that one will cough or be infected for such a long duration. The specific circumstances should be determined according to the number of infecting pathogens and the body's immune response. If the immune system is normal and the infection is minor, some patients can recover without medication. Once a severe infection is diagnosed, it is crucial to promptly use sensitive antibiotics and engage in timely anti-inflammatory and symptomatic treatment.
