Abstract:

Objective To analyze the epidemiological characteristics of pertussis in Hexi District of Tianjin City from 2014 to 2023 and predict its incidence trends,providing data support for more accurate disease prevention and control. Methods The pertussis incidence data in Hexi District of Tianjin City from 2014 to 2023 according to the date of onset were collected through the Infectious Disease Surveillance System in the China Disease Prevention and Control Information System,to analyze the epidemiological characteristics of pertussis. The Joinpoint regression model and autoregressive integrated moving average(ARIMA) model were used to analyze incidence trend and predict. Results From 2014 to 2023,a total of 322 pertussis cases were reported in Hexi District of Tianjin City,with an average annual incidence rate of 3.49/100 000. The annual percent change(APC) in the incidence rate of pertussis was 41.47% between 2014 and 2018,-63.27% between 2018 and 2021,and 1 327.35% between 2021 and 2023. The highest average annual incidence rate of 101.87/100 000 was in 0-<1 years group,but cases predominantly involved children aged 5-<10 years from 2020 to 2023.Among the 301 cases(≥3 months of age),90.70% had received at least one dose of diphthera,tetanus and acellular pertussis combined vaccine(DTaP) before pertussis onset. Among cases aged 3~<6 months,81.82% had not completed the three-dose vaccination schedule;whereas among cases aged 5-<10 years,96.97% had completed the full course of vaccination. Predict that the pertussis incidence in 2024 would be similar to that in 2023. Conclusion The reported incidence rate from 2014 to 2023 showed a trend of first increasing,then decreasing,and finally increasing again. Infants aged 0-<1 year,particularly those who had not received the DTaP vaccine or had not completed basic immunization,and children aged 5-<10 years were at high risk of pertussis. The pertussis incidence trend in 2024 was predicted to be similar to that in 2023. It is recommended to strengthen monitoring and prevention and control efforts and further explore and optimize the immunization strategy for DTaP-containing vaccines in China.
