摘要

据报道,当易感人群遇到水痘或带状疱疹病例时,就会爆发水痘带状疱疹病毒(VZV)疫情。一家拥有 50 张床位的三级综合专科医院物理医学与康复科住院部调查了一起疑似 VZV 爆发病例。2022 年 12 月 31 日,一名 30 岁的女性患者因波特脊柱炎入院,临床诊断为水痘。随后一周,同一病房又发现四例病例。所有病例均经 PCR 诊断为实验室确诊的水痘带状疱疹感染。主要病例为一名内勤人员,临床诊断为水痘 3 周前(2022 年 12 月 9 日)。他在感染后第八天(2022 年 12 月 17 日)临床症状明显好转,但皮损尚未结痂,便返回工作岗位。31 名高危工人被确定为接触者,其中 3 人没有免疫证据。其中两名易感的高危工人在接种第一剂 VZV 疫苗后不久出现水痘。所有病例均在治疗后痊愈,无并发症报告。在有易感人群的医疗机构中,VZV 感染具有高度传染性。及时发现病例并实施感染预防和控制措施(如隔离病人和接种疫苗)对于遏制疫情爆发至关重要。

Varicella zoster virus outbreak in a long-term care unit of a tertiary care hospital in northern India.

Nosocomial outbreak of varicella zoster virus (VZV) has been reported when susceptible individuals encounter a case of chicken pox or shingles. A suspected VZV outbreak was investigated in a 50-bedded in-patient facility of Physical Medicine and Rehabilitation in a tertiary care multispecialty hospital. A 30-year-old female patient admitted with Pott's spine was clinically diagnosed with chicken pox on 31 December 2022. The following week, four more cases were identified in the same ward. All cases were diagnosed as laboratory-confirmed varicella zoster infection by PCR. Primary case was a housekeeping staff who was clinically diagnosed with chicken pox 3 weeks prior (9 December 2022). He returned to work on eighth day of infection (17 December 2022) after apparent clinical recovery but before the lesions had crusted over. Thirty-one HCWs were identified as contacts a and three had no evidence of immunity. Two of these susceptible HCWs had onset of chickenpox shortly after first dose of VZV vaccination was inoculated. All cases recovered after treatment with no reported complications. VZV infection is highly contagious in healthcare settings with susceptible populations. Prompt identification of cases and implementation of infection prevention and control measures like patient isolation and vaccination are essential for the containment of outbreaks.

期刊介绍: Epidemiology & Infection publishes original reports and reviews on all aspects of infection in humans and animals. Particular emphasis is given to the epidemiology, prevention and control of infectious diseases. The scope covers the zoonoses, outbreaks, food hygiene, vaccine studies, statistics and the clinical, social and public-health aspects of infectious disease, as well as some tropical infections. It has become the key international periodical in which to find the latest reports on recently discovered infections and new technology. For those concerned with policy and planning for the control of infections, the papers on mathematical modelling of epidemics caused by historical, current and emergent infections are of particular value.
