Bordetella pertussis belongs to the genus Botrytis, which is highly infectious and has a high case fatality rate. In recent years, the number of people infected with pertussis has been increasing each year, despite the popularization of WPV vaccination in many areas. Therefore, we studied the epidemiological characteristics of pertussis in Tai'an, statistically analyzed the basic clinical data of the patients, and summarized the incidence trend of pertussis disease in Tai'an in recent years, with the aim of guiding clinicians in the diagnosis and treatment of pertussis in children. The aim of this study is to collect data and statistics on pertussis patients in terms of epidemiological characteristics, collect the basic data of pertussis patients in Tai'an Children's Hospital from March 2016 to December 2018, and analyze the epidemiological characteristics of the disease in patients in the region.From March 2016 to December 2018, a total of 1,942 patients with whooping cough were found in Tai'an Children's Hospital. The age of the population with B. pertussis infection was mainly under 6 years old, with a higher number of cases in the age groups of 3 months to 2 years old and 5 to 6 years old. The hospitalization time of the patients was 2-20 d, with an average of 12d. This study concludes that the high incidence season of pertussis infection in Taian is summer and fall. The mode of transmission has changed from the child-child transmission pattern in the past to the current adolescent/adult-neonate/child transmission pattern. The age of the population with B. pertussis infection was mainly under 6 years old, and mixed infections were common.
