To provide a descriptive audit of healthcare workers (HCWs) exposed to COVID-19, and their contacts, to understand the dynamics of transmission among HCWs.
Retrospective analysis of contact tracing data of infected HCWs was done from March 1, 2020 to July 31, 2020 at a tertiary care center in New Delhi, India. Contacts were categorized according to the nature of contact and followed for 14 days.
Qualitative RT-PCR testing was performed on 106 HCWs (from a total of 257) owing to exposure or development of symptoms. Positive results were found in 16 HCWs (6.2%) who were exposed to 120 other HCWs, generating 197 exposure incidents. Of these, 30 (15.2%) exposure incidents were high risk with multiple exposures in 48 (40.0%) HCWs. Exposure to infected HCWs was noted in 3 (18.8%) of 16 positive cases. Of the 197 exposure incidents, 54 (27.4%) were deemed avoidable exposures. Infection prevention and control policies were periodically reviewed, and the department implemented mitigating steps to minimize the risk to healthcare providers.
Instituting appropriate infection prevention and control policies and use of adequate precautions by HCWs is vital to minimize high-risk exposure to COVID-19.
对接触过 COVID-19 的医护人员（HCWs）及其接触者进行描述性审核，以了解 HCWs 之间的传播动态。
对 2020 年 3 月 1 日至 2020 年 7 月 31 日期间，印度新德里一家三级护理中心感染 HCWs 的接触者追踪数据进行回顾性分析。根据接触性质对接触者进行分类，并对其进行为期 14 天的随访。
对 106 名（共 257 名）HCWs 进行了定性 RT-PCR 检测，原因是暴露或出现症状。在 16 名 HCWs（6.2%）中发现了阳性结果，他们接触了 120 名其他 HCWs，共发生 197 次接触事件。其中 30 次（15.2%）接触事件为高风险，48 名（40.0%）HCWs 有多次接触。在 16 例阳性病例中，有 3 例（18.8%）是接触了感染的 HCWs。在 197 次接触事件中，54 次（27.4%）被认为是可以避免的接触。感染预防和控制政策定期进行审查，该科室采取了缓解措施，以最大程度地降低医疗保健提供者的风险。
实施适当的感染预防和控制政策以及 HCWs 充分使用预防措施，对于最大程度减少 COVID-19 的高风险接触至关重要。
