Interpretation of guidelines for diagnosis, management, and prevention of pertussis in China (version 2024).

The resurgence of pertussis in China has recently attracted much attention. The incidence and burden of pertussis are largely underestimated in China owing to the lack of active pertussis surveillance and insufficient laboratory diagnosis. The high prevalence of macrolide-resistant Bordetella pertussis imposes a major challenge for the management of pertussis cases. To address a series of practice issues regarding pertussis diagnosis, treatment, and prevention, especially immunization practices, a multidisciplinary guideline development group (GDG) consisting of experts in the fields of infectious diseases, pediatric critical care medicine, clinical microbiology, epidemiology, and immunization planning jointly developed the first clinical practice guidelines for pertussis in China. Utilizing the Grading of Recommendations Assessment, Development and Evaluation Evidence-to-Decision framework recommended by the World Health Organization, the GDG formulated corresponding recommendations and suggestions. Good Practice Statements were created for issues not suitable for conventional evidence rating through the presentation of evidence and expert experience. The implementation suggestions for the 12 priority clinical questions given in this paper fully considered Chinese and international experiences as well as the national situation and policy. The primary target audience of these guidelines includes clinicians, microbiology laboratory staff, public health professionals, and policymakers.
