Abstract

Background: This is one of the first studies exploring immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among blue-collar workers in Abu Dhabi.

Aims: This study estimated the seroprevalence of SARS-CoV-2 infection among workers living in a closed setting using qualitative analysis of the total SARS CoV-2 antibody immune response.

Methods: We conducted this monocentric, prospective, observational study in a labour compound for a cohort of workers between 28 March and 6 July 2020. We tested for SARS-CoV-2 (nasopharyngeal) (RT-PCR) and anti-SARS-CoV-2 T-Ab.

Results: Out of a total of 1600 workers, 1206 (75.0%) participated in the study - all were males, median age 35 years (19-63 years). We found 51% of the participants to be positive for SARS-CoV-2; the 49.0% who tested negative were considered as contacts. Anti-SARS-CoV-2 T-Ab was detected among 864 participants, showing an overall point prevalence of 71.6%. A relatively higher response was found among cases (89.0%) than among contacts (53.2%).

Conclusion: This study highlights the need to prioritize public health interventions in closed settings where disease transmission is higher due to greater overall exposure. A high seroprevalence of anti-SARS-CoV-2 T-Ab was found among the residents. A serial quantitative study applying time series and regression models is recommended to further evaluate the sustainability of the immune response among this and similar population groups.

阿拉伯联合酋长国蓝领工人SARS-CoV-2感染的血清阳性率

背景:这是阿布扎比蓝领工人对严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)免疫的首批研究之一。目的:本研究通过对SARS-CoV-2抗体总免疫反应的定性分析，估计封闭环境中工人SARS-CoV-2感染的血清阳性率。方法:在2020年3月28日至7月6日期间，我们在一个劳动力综合体中对一组工人进行了这项单中心、前瞻性、观察性研究。我们检测了SARS-CoV-2(鼻咽)(RT-PCR)和抗SARS-CoV-2 T-Ab。结果:在总共1600名工人中，1206人(75.0%)参与了研究，均为男性，年龄中位数为35岁(19-63岁)。我们发现51%的参与者对SARS-CoV-2呈阳性;49.0%检测呈阴性者被视为接触者。在864名参与者中检测到抗sars - cov -2 T-Ab，总体点患病率为71.6%。病例应答率为89.0%，接触者应答率为53.2%。结论:这项研究强调了在封闭环境中优先考虑公共卫生干预措施的必要性，在封闭环境中，由于总体暴露程度较高，疾病传播率较高。居民血清抗sars - cov -2 T-Ab阳性率较高。建议采用时间序列和回归模型进行一系列定量研究，以进一步评估这一人群和类似人群中免疫反应的可持续性。

期刊介绍： The Eastern Mediterranean Health Journal, established in 1995, is the flagship health periodical of the World Health Organization Regional Office for the Eastern Mediterranean. The mission of the Journal is to contribute to improving health in the Eastern Mediterranean Region by publishing and publicising quality health research and information with emphasis on public health and the strategic health priorities of the Region. It aims to: further public health knowledge, policy, practice and education; support health policy-makers, researchers and practitioners; and enable health professionals to remain informed of developments in public health. The EMHJ: -publishes original peer-reviewed research and reviews in all areas of public health of relevance to the Eastern Mediterranean Region -encourages, in particular, research related to the regional health priorities, namely: health systems strengthening; emergency preparedness and response; communicable diseases; noncommunicable diseases and mental health; reproductive, maternal, child health and nutrition -provides up-to-date information on public health developments with special reference to the Region. The Journal addresses all members of the health profession, health educational institutes, as well as governmental and nongovernmental organizations in the area of public health within and outside the Region.
