Pertussis, also known as whooping cough, can recover on its own if the viral load is low and symptoms are mild. However, if symptoms are more typical and accompanied by fever, difficulty breathing, and paroxysmal convulsive coughing, it generally cannot recover without medical help and requires a combination of sensitive antibiotics and symptomatic treatment. Common choices include macrolide antibiotics, such as erythromycin, clarithromycin, and azithromycin. If there are symptoms of respiratory difficulty, oxygen inhalation can be used to alleviate the signs of mucosal hypoxia.

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.

Why is whooping cough worse at night?

One reason why whooping cough is more severe at night is due to the dry air indoors which irritates, and another reason is due to changes in body posture. As the body is in a supine or lateral position during sleep at night, the bronchial mucous secretion cannot be expelled from the body, which stimulates the bronchial nerves and induces symptoms such as coughing. The typical cough is a paroxysmal spasmodic cough, and it can also lead to red face, runny nose, and in severe cases, nasal discharge, tears, nausea, and vomiting. It is necessary to receive timely anti-inflammatory treatment and maintain the cleanliness of the indoor air.

Is the pertussis vaccine an inactivated vaccine?

The pertussis vaccine is not an inactivated vaccine but a live attenuated vaccine, which primarily stimulates the body to produce antibodies. Once antibodies are produced, it can effectively prevent the disease pertussis. The commonly used pertussis vaccine in clinical settings is the trivalent vaccine, also known as the DTP vaccine, which can prevent pertussis, diphtheria, and tetanus—three infectious diseases caused by pathogens. It is essential to follow medical advice and complete the vaccination schedule as prescribed to achieve prevention. After vaccination, it is crucial to observe for any complications or adverse reactions.

How to diagnose the incubation period of pertussis

The incubation period of whooping cough generally has no autonomous discomfort symptoms. If there is close contact with a patient and the body lacks antibodies, suspecting the presence of this pathogen, corresponding auxiliary examinations can be conducted for diagnosis. Bacteriological examinations and fluorescent antibody methods can be performed, using nasopharyngeal swab secretions smear or nasal mucosa impression smear fluorescent antibody staining to detect specific antigens, with an early positive rate of 75%-85%. Complement fixation tests in serology can also be conducted to detect specific antibodies, effectively aiding in the diagnosis of atypical cases.

Whooping cough vaccine at what age?

The pertussis vaccine is generally administered within the first year of age. Under normal circumstances, children should be taken to hospitals or public health prevention stations for vaccination according to the course of treatment. The first dose starts at the third month after birth, followed by the second dose at four months and the third dose at five months old. A booster can be administered when the baby is two years old. The DTP vaccine used in clinics mainly consists of three components: pertussis, diphtheria, and tetanus.
