新型冠状病毒(SARS-CoV-2)SNV分型检测技术

SARS-CoV-2 SNV Genotyping Test Technology

新型冠状病毒肺炎(COVID-19)的全球大流行对整个人类社会造成了重大影响,人类面临着财政刺激、金融压力、债务重整等挑战。在特效治疗药物与方法出现之前,大规模的人群筛查隔离成为现在疫情治理的最有效方法。然而,这一次的新冠病毒(SARS-CoV-2)展示出了极高的遗传变异性,截至2022年3月31日统计突变率超过了2.3‰,迄今为止高传染性的新病毒株不断出现,被世界卫生组织正式警告的变异株就达到了7个。因此,在接下来的病毒防控与研究中,不但需要检测SARS-CoV-2,更需要精准、实用的单核苷酸变异(single nucleotide variation, SNV)基因分型技术,特别针对大规模人群筛查中,不仅需要获得SRAS-CoV-2的信息,还需要精准快速区分具有更高传染性与毒性的变异株感染。对病毒的感染和突变机制进行了简要介绍,并着重对现有主要的SARS-CoV-2 SNV分型技术进行了分类综述,希望为新型检测技术的开发提供参考。

The global pandemic of the COVID-19 has had a major impact on the entire human society, and human beings are facing challenges such as fiscal stimulus, financial stress, and debt restructuring. Before the emergence of specific therapeutic drugs and methods, large-scale population screening and isolation has become the most effective method for epidemic management. However, the new strain of coronavirus this time has shown a very high genetic variability, with a statistical mutation rate of more than 2.3‰ as of March 31 st, 2022. So far, new highly infectious virus strains have been emerging, and the number of mutant strains officially warned by the World Health Organization has reached 7. Therefore, in the next virus prevention and control and research, we not only need to detect SARS-CoV-2, but also need to explore accurate and practical single nucleotide variation(SNV) genotyping techniques, especially for large-scale population screening. It is not only necessary to obtain information on the SRAS-CoV-2, but also to accurately and quickly distinguish variant strains with higher infectivity and virulence. This paper briefly introduces the infection and mutation mechanism of the virus, and focuses on the classification and review of the existing main SARS-CoV-2 SNV genotyping techniques, hoping to provide insight into the development of new detection technologies.
