Whooping cough is a contagious disease, and principally transmitted from person to person. Currently, an effective way to prevent this disease is by vaccination with the DTaP vaccine. The name "whooping cough" does not mean the cough lasts for a hundred days; this is just a colloquial expression referring to its prolonged duration. The primary symptoms of this disease include severe, spasmodic coughing, during which the patient may exhibit redness in the face and ears, a runny nose, and even nausea and vomiting. Additional symptoms can include cyanosis of the lips and choking. In severe cases, it can cause whole-body convulsions leading to ischemic and hypoxic encephalopathy. Once diagnosed, it is crucial to promptly treat with antibiotics and medications that relieve bronchial smooth muscle spasms. During the acute phase, corticosteroids may also be used in treatment.
