More than 30 residents and nursing assistants in a geriatric nursing hospital developed acute gastroenteritis from December 7th to December 18th, 2014 in Shanghai, China. An immediate epidemiological investigation was conducted to identify the etiological agent of the outbreak, mode of transmission and the risk factors. Cases were investigated according to an epidemiological questionnaire. Samples from cases, highly transmissible environmental surfaces and drinking water were collected for pathogens detection. A retrospective cohort study was conducted to explore the transmission mode. A total of 34 cases were affected in this acute gastroenteritis outbreak, including 23 residents, 9 nursing assistants and 2 doctors. 13 out of 30 samples were positive for GII.17 norovirus, no other pathogen was detected. Nursing assistants who developed gastroenteritis symptoms had a higher attack rate in residents they cared than those who did not develop any gastroenteritis symptoms (p<0.001). The acute gastroenteritis outbreak was caused by GII.17 norovirus. Person-to-person close contact and contaminated environmental surfaces were the probable transmission route. Nursing assistants were considered to play an important role in the secondary spread of norovirus. The poor medical skill and personal hygiene habits of nursing assistants in China should be paid attention and improved urgently which is critically important to prevent hospital infections.
2014 年 12 月 7 日至 12 月 18 日，中国上海一家老年护理医院的 30 多名居民和护理人员发生急性肠胃炎。立即进行了流行病学调查，以确定疫情的病因、传播方式和危险因素。根据流行病学问卷对病例进行了调查。采集了病例、高度传染性的环境表面和饮用水样本进行病原体检测。还进行了回顾性队列研究以探索传播方式。此次急性肠胃炎暴发共涉及 34 例病例，包括 23 名居民、9 名护理人员和 2 名医生。30 个样本中有 13 个检测出 GII.17 诺如病毒阳性，未检测到其他病原体。发生肠胃炎症状的护理人员在照顾的居民中比未发生任何肠胃炎症状的护理人员的发病率更高（p<0.001）。急性肠胃炎暴发是由 GII.17 诺如病毒引起的。人际密切接触和污染的环境表面是可能的传播途径。护理人员被认为在诺如病毒的二次传播中发挥了重要作用。中国护理人员医疗技能差和个人卫生习惯差，应引起重视并急需改进，这对预防医院感染至关重要。
