The emergence of anovel coronavirus identified in patients with unknown cause of acute respiratory disease in Wuhan, China at the end of 2019 has caused aglobal outbreak. The causative coronavirus was later named as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the disease caused by SARS-CoV-2 was named as Coronavirus Disease-2019 (COVID-19). As of 10 August 2020, more than 19,718,030 confirmed cases and 728,013 deaths have been reported. COVID-19 is spread via respiratory droplets which are inhaled into the lungs.
In this article, we summarized the knowledge about the causative pathogen of COVID-19 and various diagnostic methods in this pandemic for better understanding of the limitations and the nuances of virus testing for COVID-19.
In this pandemic, rapid and accurate identification of COVID-19 patients are critical to break the chain of infection in the community. RT-PCR provides a rapid and reliable identification of SARS-CoV-2 infection. In the future, molecular diagnostics will still be the gold standard and next-generation sequencing can help us to understand more on the pathogenesis and detect novel mutations. It is believed that more sophisticated detection methods will be introduced to detect SARS-CoV-2 as earliest as possible.
2019 年底,在中国武汉,不明原因急性呼吸道疾病患者中发现了一种新型冠状病毒,引发了全球疫情。这种致病冠状病毒随后被命名为严重急性呼吸综合征冠状病毒 2(SARS-CoV-2),由 SARS-CoV-2 引起的疾病被命名为 2019 冠状病毒病(COVID-19)。截至 2020 年 8 月 10 日,全球已报告超过 1971.803 例确诊病例和 72.8013 例死亡病例。COVID-19 通过吸入肺部的呼吸道飞沫传播。
本文总结了 COVID-19 的病原体及目前各种诊断方法,以便更好地了解 COVID-19 病毒检测的局限性和细微差别。
在这场大流行中,快速准确地识别 COVID-19 患者对于阻断社区感染链至关重要。实时 RT-PCR 为 SARS-CoV-2 感染提供了快速可靠的鉴定。在未来,分子诊断仍将是金标准,而下一代测序可以帮助我们更好地了解发病机制并检测新的突变。相信将有更复杂的检测方法被引入,以便尽早检测到 SARS-CoV-2。
