Pertussis, commonly known as whooping cough, is a prevalent infectious respiratory disease in children. If the disease is suspected, one can visit a nearby public hospital for a physical examination. Tests can include a complete blood count and erythrocyte sedimentation rate, as well as a sputum culture to identify pathogens such as Corynebacterium diphtheriae and Bordetella pertussis for diagnosis. Typical symptoms include a cough resembling a dog's bark or a crowing sound. Prompt treatment with macrolide antibiotics and cough suppressants and expectorants is necessary to alleviate discomfort.
