Knowledge, attitudes, and practices regarding chikungunya fever among healthcare workers: a cross-sectional study in Sichuan Province, China

Objective To assess the knowledge, attitudes, and practices (KAP) of healthcare workers (HCWs) regarding Chikungunya fever and its influencing factors in non-endemic Sichuan Province, China. Methods A cross-sectional online survey was conducted among 312 HCWs in August 2025. Data were collected using a structured KAP questionnaire and analyzed with descriptive statistics, chi-square tests, binary logistic regression, and correlation analyses. Results The great scores rates for knowledge, attitudes, and practices were 60.90%, 65.38%, and 40.06%, respectively. Knowledge was positively correlated with attitudes ( r = 0.403, p < 0.001), and attitudes with practices ( r = 0.661, p < 0.001). Knowledge was significantly higher among physicians (OR = 1.607) and secondary hospital staff (OR = 1.901). Senior professional title and 5–10 years of work experience were associated with more positive attitudes. Although most HCWs recognized the importance of prevention (94.88%) and had high learning willingness (90.06%), practical performance was low—only 34.97% regularly conducted public health education. Conclusion Significant gaps exist in core knowledge and its translation into practice among HCWs in non-endemic areas. Targeted training, especially for nurses and primary care providers, is urgently needed to enhance outbreak preparedness.
