所有国家都投入了大量努力来应对 COVID-19 大流行,包括追踪感染者、遏制疾病传播、确定治疗方法以及生产和分发疫苗。目前,一个重大问题是病毒变体的出现,这些变体可能会表现出传播性增加、疾病严重程度增加、对治疗或疫苗的反应减弱以及逃避诊断的能力,从而挫败这些努力。因此,各国都投入了大量的努力来识别和追踪这些变异,这需要大量的技术努力来对大量病毒基因组进行测序。在本文中,我们报告了我们作为参与 SARS-CoV-2 变异追踪的意大利实验室之一的经验。我们总结了所使用的不同方法,并概述了一个结合多种技术的潜在模型,以提高跟踪能力,同时最大限度地降低成本。
A considerable effort has been devoted in all countries to react to the COVID-19 pandemic by tracing infected individuals, containing the spread of the disease, identifying therapies, and producing and distributing vaccines. Currently, a significant concern is the appearance of variants of the virus that may frustrate these efforts by showing increased transmissibility, increased disease severity, reduced response to therapy or vaccines, and ability to escape diagnosis. All countries have therefore devoted a massive attempt to the identification and tracking of these variants, which requires a vast technological effort to sequence a large number of viral genomes. In this paper, we report our experience as one of the Italian laboratories involved in SARS-CoV-2 variant tracing. We summarize the different approaches used, and outline a potential model combining several techniques to increase tracing ability while at the same time minimizing costs.
