Epidemiological investigation on an outbreak of 3 cases of measles infected in hospital

目的调查上海市某医院肝脏外科儿童病区内麻疹感染暴发的原因。方法对该院肝脏外科儿童病区2014年5月4~15日发生的3例麻疹确诊病例的病历资料进行回顾性调查分析。结果 3例麻疹患儿麻疹病毒Ig M抗体检测均阳性。3例患儿同住该院肝脏外科儿童病区,住院时间均超过麻疹的最长潜伏期,发病时间间隔不超过麻疹的最短潜伏期。结论此次事件属于一起医院感染的暴发事件,但未发现明显的共同传染源。建议加强关注患有基础性疾病儿童的麻疹早期诊断。做好包括医技科室在内的发热预检、通风消毒工作,避免造成麻疹病例交叉感染。

Objective To investigate the causes of an outbreak of measles in a pediatric liver transplantation ward of a hospital in Shanghai, China. Methods Medical data of 3 cases of measles in a pediatric liver transplantation ward from May 4 - 15, 2014 were analyzed retrospectively. Results All the measles virus antibody IgM were positive in 3 children. The time durations of hospital stays of 3 children were longer than the longest latent period of measles （21 d）, while the onset time intervals were shorter than the shortest latent period of measles （7 d ）. Conclusion This event was a hospital infection outbreak. However, no obvious source of common infection was found. The early diagnosis of measles in the children with basic diseases should be paid more attention. The pre-inspection on fever and ventilation disinfection in the ancillary departments should be strengthened to avoid the cross-infection of measles cases.
