At the beginning of the coronavirus disease 2019 (COVID-19) pandemic in Bangladesh, there was a scarcity of ideal biocontainment facilities to detect the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a risk group of 3 organisms. Molecular detection of SARS-CoV-2 must be performed in a BSL-2 laboratory with BSL-3-equivalent infection prevention and control practices. Establishing these facilities within a short timeframe proved to be an enormous challenge, including locating a remote space distant from the university campus to establish a laboratory, motivating the laboratory staff to work with a novel pathogen without any prior experience, allocation of funds for essential equipment and accessories, and arrangement of a safe waste management system for environmental hazard reduction. This report also highlights several limitations, such as the facility's architectural design that did not follow the biosafety guidelines, lack of continuous flow of funds, and an inadequate number of laboratory personnel. This article describes various efforts taken to overcome the challenges during the establishment of this facility that may be adopted to create similar facilities in other regions of the country. Establishing a BSL-2 laboratory with BSL-3-equivalent infection prevention and control practices will aid in the early detection of a large number of cases, thereby isolating persons with COVID-19, limiting the transmission of SARS-CoV-2, and promoting a robust public health response to contain the pandemic.
在孟加拉国 2019 年冠状病毒病(COVID-19)大流行之初,缺乏理想的生物安全隔离设施来检测严重急性呼吸综合征冠状病毒 2(SARS-CoV-2),这是 3 种危险群生物之一。SARS-CoV-2 的分子检测必须在生物安全二级(BSL-2)实验室中进行,并采取相当于生物安全三级(BSL-3)的感染预防和控制措施。在短时间内建立这些设施被证明是一项巨大的挑战,包括寻找远离大学校园的偏远空间来建立一个实验室,激励实验室工作人员在没有任何先前经验的情况下处理新型病原体,为必要的设备和附件分配资金,以及安排安全的废物管理系统以减少环境危害。本报告还强调了一些限制因素,例如设施的建筑设计不符合生物安全指南、资金持续流动不足以及实验室人员数量不足。本文描述了在建立该设施过程中克服挑战所采取的各种措施,这些措施可能被用于在该国其他地区建立类似的设施。建立一个具有相当于生物安全三级的感染预防和控制措施的生物安全二级实验室,将有助于早期发现大量病例,从而隔离 COVID-19 患者,限制 SARS-CoV-2 的传播,并促进强有力的公共卫生应对措施来控制大流行。
