Objective To evaluate the application of disinfection in infection prevention and control at a CDC, providing evidence for improving infection management. Methods A retrospective study was conducted on disinfection measures implemented at Fuxin CDC from January to December 2024. Participants included staff and visitors, divided into a control group (n=150) and an intervention group (n=160). The intervention group implemented standardized measures for surface, air, hand hygiene, and equipment disinfection. Indicators compared included airborne bacterial counts, surface culture qualification rates, and hand hygiene compliance. Statistical analysis was performed with SPSS 26.0. Results Airborne bacterial counts were significantly lower in the intervention group (42.7±8.3 CFU/m³ vs. 89.5±10.6 CFU/m³, P<0.001). Surface qualification rates improved (97.5% vs. 82.0%, P=0.003), and hand hygiene compliance increased from 66.7% to 92.3% (P=0.002). Conclusion Standardized disinfection significantly reduces microbial contamination and infection risk in CDCs, and should be widely promoted in public health institutions.
