Current strategy of SARS-CoV-2 molecular detection Lei Xie, Junlin Li, Ying Ai, Haolan He, Xiuyun Chen, Mingyu Yin, Wanxi Li, Wenguan Huang, Minyi Luo and Jinyang He Abstract Molecular detection of the SARS-CoV-2 is extremely important for the discovery and prevention of the pandemic dissemination.
