Pertussis (or whooping cough) is a highly infectious acute respiratory disease primarily caused by Bordetella pertussis, which is also one of the most important causes of infant death worldwide. The widespread use of vaccines has greatly reduced the morbidity and mortality of pertussis. However, since the 1980s, in a number of countries with high vaccine coverage, the incidence of pertussis has risen again after remaining low for many years, with outbreaks even occurring in some areas. The peak onset of pertussis is shifting from infancy to adolescence, and adolescence is becoming the main source of infection for infants. Despite the increasing incidence of pertussis, serological findings suggest that the true prevalence of the disease may be significantly underestimated. Therefore, in this narrative review, we summarize the pathogenic process and immune characteristics of bacteria, the diagnosis and treatment of diseases, as well as vaccination and prevalence of pertussis at home and abroad, and attempt to analyze the causes and influencing factors of pertussis resurgence and summarize some prevention and control strategies to assist in improving the understanding of pertussis and preventing unexpected outbreaks.
