Abstract: Objective To analyze the results of syphilis infection detected in a hospital between 2014 and 2018 for evidence to plan prevention and control measures. Methods The clinical data were collected from inpatients in our hospital undergone syphilis test between January 2014 and December 2018, and retrospectively analyzed. Results Totally, 73 648 inpatients received syphilis test in 5 years. Positive results were found in 2 144(2. 91% ) by TP-ELISA. Double positive serum (0.67% ) was seen in 494 inpatients tested by both TP-ELISA and TRUST. The infection was higher in males than in females,and the highest positive rate was observed in inpatients aged over 60 years. Additionally, the highest involvement was the Anorectal Department, followed by ICU, Department of Respiratory Medicine, Neurology Department and Ophthalomogy Department. TRUST titer≥1 ∶ 8 accounted for 33. 98% in patients aged 41~50 years. Conclusion Enhanced knowledge on and test of syphilis should be given to the inpatients, especially the elderly male patients, so that they can obtain early diagnosis and treatment. In addition, medical providers in the sections with higher rate of syphilis detected should practice better self-protection in order to reduce risks of occupational exposure.
