If whooping cough has been cured, generally, it won’t infect a person again. However, clinically, a small number of patients might get infected again due to weak immunity, though such cases are relatively rare.

Whooping cough is caused by an infection with Bordetella pertussis and is an acute respiratory infectious disease. The source of infection in whooping cough is the patient themselves, and the disease can spread through airborne droplets. Most people who contract this disease will develop corresponding antibodies, so generally, they will not get infected again after recovery.

However, some patients with weak constitutions and low immunity might not develop sufficient antibodies after the initial infection, which can potentially lead to a reinfection.

Whooping cough belongs to which type of infectious disease?

Pertussis, also known as whooping cough, is an acute respiratory infectious disease caused by the infection of Bordetella pertussis. It is categorized as a Class B infectious disease according to national regulations. Bordetella pertussis has weak resistance to external environments and is generally not considered to spread through indirect contact. The primary mode of transmission is through respiratory droplets. Asymptomatic infected children are the main transmitters of the disease. Children under the age of five are the most susceptible. Babies typically receive their primary immunization at the ages of 3, 4, and 5 months, a booster immunization at 18-24 months, and another booster at the age of 6.

Is whooping cough contagious?

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.
