目的：了解综合医院传染病分布情况，减少因传染病引起的医院感染。方法以2005－2012年某三甲医院网络直报传染病病例为研究对象，通过统计描述分析传染病流行特征。结果 HIV 病毒感染、丙肝和手足口病构成比有上升趋势，流行性腮腺炎、手足口病、水痘和感染性腹泻平均年龄分别为（7．8±6．3）岁、（2．9±3．4）岁、（12．7±9．0）岁、（7．1±14．5）岁，来自其他省病例构成比最高的传染病为 HIV 感染（20．8％）、其他（3．6％）、丙肝（3．4％）。结论流行性腮腺炎、手足口病、水痘和感染性腹泻发病年龄较小，易形成聚集，HIV 感染、丙肝和乙肝因人口流动性增加而多为输入病例，可通过识别高危人群，加强医院感染管理切断传播途径，保护易感人群。“,”Objective To Exploring the distribution of communicable diseases in the general hospital to reduce hospital infection caused by communicable diseases.Methods The 2005 -2012 network report cases of communicable diseases were research object and the statistical description was used to analysis the epidemic characteristics.Results The number of HIV infection ca-ses,hepatitis C infection cases and the hand,foot and mouth disease(HFMD)had the rising trend,the ages of mumps,HFMD,chickenpox,and infectious diarrhea were (7.8 ±6.3),(2. 9 ±3.4),(12.7 ±9.0)and (7.1 ±14.5)respectively,and the highest proportion diseases of cases coming from other provinces were HIV infection(20.8%),other diseases(3.6%),and hepatitis C(3.4%).Conclusion Mumps,HFMD,chickenpox,and infectious diarrhea in young people can form aggregation easily,and HIV infection,hepatitis C and hepatitis B were usual y imported diseases,so identifying high -risk groups and strengthening the hospital infection management can cut of the transmission and protect the vulnerable population.
