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.

Can whooping cough be vaccinated against?

Pertussis can be prevented with a vaccination and is a type of respiratory infectious disease. The main clinical preventive measure is vaccination, specifically with the DTP vaccine, which is a national Category I vaccine and part of basic immunization. The first dose should be administered when the baby is three months old. The DTP vaccine prevents not only pertussis but also diphtheria and tetanus infections. The complete course consists of three injections, with the second and third doses administered in the fourth month and between the fourth and fifth months, respectively.

whooping cough symptoms

Whooping cough is a common respiratory infectious disease, mainly caused by infection with Bordetella pertussis. Typical symptoms include colds, runny nose, etc., and feature paroxysmal coughing. The main characteristic is paroxysmal, spasmodic coughing that occurs in strings, with more than ten or even dozens of coughs at a time. The coughing increases abdominal pressure, leading to nausea and vomiting. Infants and young children may also experience a barking cough and wheezing. Some may also experience symptoms such as urinary and fecal incontinence, flushed face, runny nose, teary eyes, and cyanosis of the lips. Once diagnosed, it is important to promptly select sensitive antibiotics for anti-inflammatory treatment. Currently, the main approach to managing this disease is prevention, including timely vaccination against whooping cough.

Symptoms and Treatment of Whooping Cough in Children

The common symptoms of whooping cough are coughing, prolonged coughing, and spasmodic coughing, which ends with a crowing sound, and it mainly occurs during the night. The face may turn bright red during coughing, which is a typical symptom of whooping cough. For treatment, in the early stages of whooping cough, erythromycin is definitely used and can be effective. However, in pediatrics, if the whooping cough has lasted for a long time, the effectiveness of the treatment is relatively not as good. If the coughing period is long and medication is used in the middle to late stages, even with some treatment, it might still continue for two to three months. Although treatments like cough suppressants and expectorants can alleviate the symptoms, a cough usually still persists to some degree.

Does whooping cough require hospitalization for treatment?

This particular disease cannot be certain whether hospitalization is needed; it depends on the severity of the disease, the patient's constitution, the duration of the illness, and the body's sensitivity to the pathogens. If it is just mild paroxysmal spasmodic coughing without persistent high fever, breathing difficulty, or hypoxia, hospitalization is generally not necessary. Treatment can be managed at home with oral medication or nebulized inhalation for symptomatic treatment. The main principle is to eradicate the Bordetella pertussis bacteria.

Will there be shadows in the lungs after recovery from whooping cough?

Whooping cough is an acute respiratory infectious disease caused by Bordetella pertussis infection, commonly seen in children, with children under five years old being the most susceptible. The main clinical symptoms include paroxysmal spasmodic coughing and a crowing, inspiratory whoop, with the cough being more pronounced at night. The symptoms of whooping cough are severe, but the physical signs are mild. During lung auscultation, no dry or moist rales can generally be heard, and imaging examinations are also normal. However, whooping cough may be complicated by bronchopneumonia, bronchiectasis, and other complications, in which case lung X-rays may show shadows, but these shadows will disappear after recovery from the treatment.
