Abstract:

Objective To understand the epidemiological characteristics of pertussis in Binzhou City,and provide support for formulating prevention and control strategies of pertussis in Binzhou City. Methods The reported cases of pertussis in Binzhou City from 2017 to 2023 were collected through the National Health Security Disease Control and Prevention Information System,and descriptive epidemiological analysis methods were used to study the spatial,temporal,and demographic distribution characteristics of the reported pertussis cases in Binzhou City from 2017 to 2023. Results From 2017 to 2023,1 918 cases of pertussis were reported in Binzhou City,with no deaths,and the average annual pertussis incidence was 6.92/100,000. There was a statistically significant difference in the reported incidence rate of pertussis between different years(P<0.01). The highest incidence rate was reported in Huimin County(15.31/100 000),while the lowest incidence rate was reported in Boxing County(2.64/100,000). There was a statistically significant difference in the incidence rate of pertussis among people in different counties(cities,districts)(P<0.01). The onset of the disease was mainly concentrated from July to November,with a slightly higher incidence in male patients than in females,but there was no significant difference in the incidence rate between the two(P>0.05). The age of onset was mainly concentrated in children aged 0-<10 years old,with a total of 1 831 cases,accounting for 95.5% of the total number of cases. Among all reported cases,1 913 cases were reported among scattered children,children in nursery,and students,accounting for 99.74% of the total number of reported cases. Among the reported cases,1 232 cases had received 4 doses of the pertussis vaccine,accounting for 64.24%. Conclusion The incidence of pertussis in Binzhou City is showing an upward trend,with an increasing number of cases in older children. Children and students remain the key populations for pertussis prevention and control. It is recommended to strengthen the surveillance of pertussis,do a good job in routine immunization and catch-up vaccination of pertussis vaccine,explore and improve pertussis immunization strategies,and optimize immunization program,strengthen training,improve the diagnostic and reporting capabilities of medical institutions for pertussis,and continuously promote health education and publicity work to achieve effective control of the epidemic.
