Abstract:
Objective To analyze the epidemic and clinical characteristics of pertussis cases in Changping District, Beijing and improve the clinical diagnosis level, and to provide a scientific basis for pertussis prevention and control. Methods Descriptive epidemiological methods were used to analyze pertussis cases in Changping District, Beijing from 2023 to 2024. Results A total of 565 cases were reported in Changping District, Beijing from 2023 to 2024, with an average annual incidence of 12.45/100 000. There were 285 males (50.44%) and 280 females (49.56%). The top five towns and streets with the highest number of reported cases were Beiqijia (90 cases), Longzeyuan (71 cases), Shahe (57 cases), Huilongguan (48 cases) and Tiantongyuan South (46 cases), accounting for 55.22% of all cases. The top three towns and streets with the highest incidence rate were Tiantongyuan South (19.72/100 000), Longzeyuan (19.49/100 000) and Beiqijia (14.55/100 000). The incident peak period was from October 2023 to April 2024, with a total of 422 cases reported, accounting for 74.69%. The age of cases ranged from 29 days to 73 years old. There were 67 cases under 1 year old, with the highest incidence rate (263.10/100 000), followed by the 5-9 years old group (149.98/100 000). The 5-9 years old group had the highest proportion of cases, accounting for 301 cases (49.05%). A total of 513 cases (90.80%) had a history of pertussis vaccine immunization, and 455 cases (80.53%) had been vaccinated with 4 doses of pertussis vaccine. The median interval from onset to diagnosis of whooping cough was 18 days and the median duration of cough was 11 days. Conclusion The highest incidence of pertussis is among infants under 1 year old, followed by the 5-9 years old group. Children of appropriate age should be vaccinated in time according to the latest national immunization strategy. Medical institutions should improve diagnostic capability and increase monitoring sensitivity.
