What is pertussis

First: pertussis is an acute respiratory infectious disease caused by Bacillus pertussis. Its clinical feature is paroxysmal spasmodic cough accompanied by deep "cockcrow" like inspiratory roar. If it is not treated in time and effectively, the course of disease can be delayed for several months, so it is called "pertussis". Patients are the only source of infection, including typical patients and mild patients.

Second: pertussis is not easy to survive in the external environment. It can only grow and propagate in the upper respiratory tract mucosa and spread with droplets. Therefore, the transmission of pertussis is mainly through droplets when coughing. It is possible to inhale bacteria within 2m around the patient.

Third: pertussis bacteria die quickly in vitro. Therefore, it is rarely transmitted indirectly through clothing, appliances, etc. In addition, people are generally susceptible to pertussis, especially in children. This is because there is no pertussis antibody transmitted from the placenta to the fetus during pregnancy, so the newborn can be infected with the disease after birth. The younger the age is, the higher the mortality rate is. After suffering from pertussis, we can get persistent immunity. It is rare to get two cases of pertussis in our life.
