An Outbreak of Neonatal Rotavirus Gastroenteritis:A Bundle of Practices for Infection Prevention and Control

目的通过对一起新生儿轮状病毒肠炎暴发事件的调查处置,总结防控经验,为预防、控制该类事件的发生、发展提供依据。方法对2022年6月23日—6月25日发生轮状病毒肠炎的5例新生儿进行流行病学调查和环境卫生学监测,寻找危险因素,采取控制措施。结果该期间入住新生儿室患儿共78例,发生轮状病毒肠炎5例,罹患率6.41%,该事件持续10 d,三间分布有明显聚集性,环境和手的污染是造成感染暴发的重要因素。结论该事件是一起由轮状病毒感染引起的疑似医院感染暴发事件,通过更换手消毒剂产品、提高医务人员手卫生依从性、加强高频接触点环境清洁消毒、采取接触隔离措施等防控手段使感染得到有效控制。
