摘要
目的建立流行性腮腺炎医院感染动力学模型,为综合医院儿科流行性腮腺炎防控措施的采用和防控时间的选择提供理论支持。方法以综合医院儿科为研究背景,根据流行性腮腺炎的传播特征,采用MATLAB软件建立自然传播和采取隔离措施两种情况下的SEIR模型。结果流行性腮腺炎医院自然传播情况下第3天可能出现医院感染爆发,院感爆发后采取隔离措施可在第4天减少易感者感染,第21天不再发生新发病例。结论流行性腮腺炎易形成医院感染爆发,采取隔离措施能有效控制其传播,早发现、早隔离流行性腮腺炎患儿,做好综合医院预检分诊和隔离能够避免流行性腮腺炎医院感染。
OBJECTIVE To establish epidemic dynamics model of hospital acquired mumps,so as to provide theoretical support for the selection of control measures and opportunities in department of pediatrics of general hospital.METHODS The SEIR models,which included two cases：natural transmission and taking quarantine measures,following the propagation characters of mumps,was builded by MATLAB software,and the background was department of pediatrics in general hospital.RESULTS Mumps maight have outbreak on the 3rd day under the natural condition in hospital,on the 4th day the number of susceptibles decreased and no one infected on the 21 st day if the quarantine measures were taken.CONCLUSION Mumps can easily break out in hospital,disinfection and quarantine can effectively control the nosocomial spread of mumps.Early discovery and quarantine on children with mumps and make triage after pre-examination and quarantine could avoid mumps in children outbreak in hospital.
