Objective To evaluate the correlation between occupational exposure and work intensity of health care workers(HCWs)in an infectious diseases hospital for 5 consecutive years,and provide reference for occupational precaution.Methods Occupational exposures cases reported between January 2010 and December 2014 were ana-lyzed retrospectively,occupation types,exposure routes,and exposure sources were analyzed.Results A total of 228 cases of occupational exposure were reported,nurses and doctors were the major exposure population(75.44%and 19.30% respectively);occupational exposure mainly occurred during the infusion process(52.19%);hepatitis B was the main exposure source (71 .05%),followed by human immunodeficiency virus (10.09%).The Pearson correlation coefficient between the occupational exposure rate of doctors and the ratio of doctors to patients was-0.849 (P <0.05),and for nurses,the correlation coefficient was -0.823 (P <0.05 ).Conclusion Nurses are high risk population of occupational exposures,occupational exposure is most likely to occur during transfusion process,occupational exposure of doctors and nurses has a strong correlation with the work intensity.

Objective: To explore the risk factors of occupational exposure of intern nurses in an infectious disease hospital, and put forward prevention and control strategies. Methods: A retrospective analysis was made of 82 reported cases of occupational exposure of intern nurses in a tertiary infectious disease hospital from 2013 to 2017. The occupational exposure rate, pathogens, occurrence sites and exposure links of the intern nurses were analyzed. Results: The overall occupational exposure rate of internship nurses in 2013-2017 was 6.20% (82/1322) .The pathogens were mainly HBV, 52 cases, accounting for 63.4%. The site of occurrence was mainly finger, 75 cases, accounting for 91.5%. In the occurrence of the process, 35 cases were taken, accounting for 42.7%; 20 cases of arteriovenous puncture, accounting for 24.4%; 17 cases of separation needles and finishing materials, accounting for 20.7%. Conclusion The incidence of blood-borne occupation of intern nurses is higher, which needs special attention in infectious disease hospitals. To prevent blood-borne occupational exposure of intern nurses, occupational safety education should be strengthened, clinical operation should be standardized and humanized management should be provided.
