Abstract：
Health care workers (HCWs) may be at a variable risk of SARS-CoV2 infection. Regardless of their involvement in providing direct clinical treatment, most of the prior research had included all HCWs. Understanding infection rates, risk factors and outcomes among different subgroups of HCWs is crucial. From February 28, 2020 to January 1, 2022, we conducted a retrospective analysis encompassing all full-time non-clinical staff (NCS) subcontracted with Hamad Medical Corporation (HMC) facilities. To determine current or previous SARS-CoV2 infection, all personnel underwent RT-PCR and/or serology testing. To identify the demographic factors linked to the risk of infection, we utilized Cox-Hazard regression analysis. Herein 3158/6231 (50.7%) subcontracted NCS tested positive for SARS-CoV-2 by RT-PCR or serology during the research period. The median age was 30 years (IQR 25,35), 69.8% of the population were males, 82.4% were from South Asia, 86.6% did not have any concomitant conditions. 6032 (96.8%) of the population lived in shared housing, while 4749 (76.2%) had low to median levels of education. While infection (PCR positive with or without seropositive results) was independently predicted by male gender, working in the catering, laundry, and security sectors and being intermediate (7-12 years of education), lower (0-6 years of education), higher (exposure to confirmed case), and having symptoms. Male gender, working in the security sectors and being intermediate (7-12 years of education) were independently associated with accidently detected cases (PCR negative and seropositive). 299 (4.8%) required hospitalization, of them 3 cases were severe pneumonia and one required ICU admission without mechanical ventilation, with no deaths reported. In conclusion Infection rates among NCS are high. The majority are asymptomatic and may contribute to ongoing illness spread in the public or in healthcare facilities. During a pandemic, routine screening of this population is crucial and may aid in containing the spread of infection.
摘要：
医护人员（HCWs）可能面临SARS-CoV2感染的可变风险。不管他们参与提供直接的临床治疗，以前的大部分研究都包括了所有HCWs.了解感染率，不同HCWs亚组的危险因素和结局至关重要.从2020年2月28日至2022年1月1日，我们进行了一项回顾性分析，包括与哈马德医疗公司（HMC）设施分包的所有全职非临床工作人员（NCS）。为了确定当前或以前的SARS-CoV2感染，所有人员均接受RT-PCR和/或血清学检测.为了确定与感染风险相关的人口统计学因素，我们使用Cox-Hazard回归分析。在研究期间，3158/6231（50.7％）分包的NCS通过RT-PCR或血清学检测出SARS-CoV-2阳性。中位年龄为30岁(IQR25,35)，69.8%的人口是男性,82.4%来自南亚，86.6%没有任何伴随条件。6032(96.8%)的人口居住在共享住房中，而4749人(76.2%)的教育水平低至中位数。虽然感染（PCR阳性，有或没有血清阳性结果）由男性独立预测，在餐饮业工作，洗衣房,和安全部门，处于中等水平(7-12年教育)，较低（0-6年的教育），更高(暴露于确诊病例)，并有症状。男性,在安全部门工作和处于中等水平(7-12年教育)与意外检测到的病例(PCR阴性和血清阳性)独立相关.299（4.8%）需要住院治疗，其中3例为重症肺炎，1例为未接受机械通气而需入住ICU，没有死亡报告。总之，NCS的感染率很高。大多数是无症状的，可能导致正在进行的疾病在公众或医疗机构中传播。在大流行期间，对该人群进行常规筛查至关重要，可能有助于遏制感染的传播。
