摘要
Pertussis(whooping cough)is an acute and contagious respiratory disease caused by the pathogen Bordetella pertussis(B.pertussis).B.pertussis can infect individuals of all ages.Children with pertussis may experience severe and persistent coughing and paroxysms;for newborns and infants,pertussis may be life-threatening.The development and widespread administration of the pertussis vaccine had once successfully brought pertussis under control,maintaining it at a low level for many years.However,resurgence of pertussis has been reported in many countries even with high vaccination coverage recently.The resurgence of pertussis was first reported in the United States(USA)in 1993[1].During 2000–2016,the baseline incidence increased and the age distribution of pertussis changed in the USA[2].Other countries including Canada[3],Australia[4],European Union countries,and South Korea have also reported a rise in pertussis outbreaks[2,5].
