The most common complications of pertussis infection include apnea, pneumonia and weight loss (secondary to eating difficulties and vomiting after coughing). Other complications include seizures, encephalopathy, death, difficulty sleeping, pneumothorax, nosebleeds, subconjunctival hemorrhage, subdural hematoma, rectal prolapse, urinary incontinence and rib fracture. A rare fever or only a brief low fever during pertussis. If there is obvious fever, it is usually recommended to infect other pathogens.

The main complications of whooping cough are bronchitis and pneumonia. In severe cases, atelectasis and toxic encephalopathy may occur. Pertussis is caused by Bordetella pertussis infection. Its main feature is spasmodic cough. When coughing is serious, you can hold your breath and suffocate, some can twitch, and severe cases can cause intracranial hemorrhage. Therefore, while carrying out anti-inflammatory treatment, coughing is very important. At the same time, it is necessary to prevent suffocation, find someone to take care of it, and avoid accidents when convulsing and coughing.

There are two modes of transmission of pertussis: ① Breathing foam can be transmitted by sneezing, talking loudly, coughing and inhaling Bordetella pertussis. ② It can be spread by splashing bubbles such as aerosol, talking loudly and coughing. Small particles smaller than 5μm can be suspended in the air for a long time. If the environment is relatively closed and the air is not circulating, it can be infected by inhaling aerosols in the air. The main sources of infection of pertussis are patients, latent infections and carriers of pertussis bacteria. Infectious can start from the incubation period until the sixth week of the course. The most contagious is 2-3 weeks after onset.

Pertussis is a bacterial infectious disease transmitted through respiratory tract, which can be prevented by vaccination. Pertussis vaccine includes whole-cell pertussis vaccine and acellular pertussis vaccine. At present, the pertussis vaccine used in China belongs to acellular pertussis vaccine. The immunization program is to complete 3 injections within 6 months after the baby is born, 1.5-2 years old 1 injection to strengthen immunity. At present, the increase of pertussis may be due to incomplete vaccine coverage and lack of routine immune enhancement for adolescents and adults. Therefore, it is necessary to improve the understanding of whooping cough, strengthen the management and vaccination of older children and adolescents, and effectively control the occurrence of whooping cough.
