What is pertussis

First of all, pertussis is an acute respiratory infectious disease caused by pertussis bacillus. Since the extensive implementation of pertussis vaccine immunization, the incidence of this disease has been greatly reduced. The clinical feature of pertussis is that the cough gradually worsens, showing typical paroxysmal and spasmodic cough. At the end of the cough, there is a deep and long cockcrow like inspiratory roar. The course of the disease is as long as 2-3 months, so it is called pertussis.

Secondly, it is generally caused by the infection of Bordetella pertussis (referred to as Bordetella pertussis), and it can also be caused by the same genus of Bordetella pertussis and Bordetella parapertussis. Bordetella pertussis is a gram-negative bacterium, which can produce some pathogenic substances, including pertussis toxin, tracheotoxin, adenylate cyclase toxin, thermolabile toxin and endotoxin. Pertussis toxin can mobilize lymphocytes from patients' lymphoid tissue to peripheral blood and trachea. Cytotoxin can specifically damage tracheal ciliated epithelial cells, causing degeneration and necrosis.

Finally, in recent years, pertussis will also appear in adults and teenagers, not only cough, but also cough vomiting phenomenon, but also only a few weeks dry cough, rare complications. Most patients can still insist on work, although I have no much pain, but can be used as a source of infection, especially a threat to children, should be paid attention to.
