Dengue Fever Screening Awareness and Capacity in Healthcare Facilities - Guangzhou City, Guangdong Province, China, 2024.

Abstract

What is already known about this topic?: Dengue fever represents a significant public health challenge in tropical and subtropical regions globally, including China. The effective management of dengue cases depends critically on accurate and timely clinical and laboratory diagnosis, supported by well-coordinated healthcare services.

What is added by this report?: This survey revealed that healthcare facilities still needed to enhance dengue case screening and public health education initiatives. Polymerase chain reaction testing capacity was severely insufficient and inconsistent reimbursement rates across health insurance types and institutional levels. Notably, significant variations in dengue diagnostic awareness existed across hospital levels, departments, ages, and professional titles (P<0.05). Targeted training significantly enhanced diagnostic competence [odds ratio (OR)=13.78, 95% confidence interval (CI): 2.94-64.65].

What are the implications for public health practice?: Healthcare facilities must maintain heightened vigilance during dengue fever outbreaks. Robust screening and diagnostic capabilities are essential for early case detection and management. Understanding and addressing identified deficiencies and their contributing factors can strengthen the response capabilities while offering valuable lessons for other regions.
