The Drug Administration Law of the People's Republic of China (amended in August 2019) is a major piece of legislation governing drug administration in China. This law seeks to improve health legislation; to achieve this, it defines the concepts of fake drugs and inferior drugs and their differences, it emphasizes the regulation of reliability, it standardizes online drug sales, it encourages technological innovation, and it specifies legal liability and punishment through legislative amendments. The Drug Administration Law is characteristic of responsive legislation, and it guarantees a right to health for citizens. The law provides for priority review and approval of new drugs for diseases like rare diseases, it encourages the domestic manufacturing and development of new drugs for rare diseases, and it provides a firm legal basis for medications to treat rare diseases under the Healthy China strategy.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly spread and poses a major threat to public health worldwide. The whole genome sequencing plays a crucial role in virus surveillance and evolutionary analysis. In this study, five genome sequences of SARS-CoV-2 were obtained from nasopharyngeal swab samples from Zhengzhou, China. Following RNA extraction and cDNA synthesis, multiplex PCR was performed with two primer pools to produce the overlapped amplicons of ~1,200 bp. The viral genomes were obtained with 96% coverage using nanopore sequencing. Forty-five missense nucleotide mutations were identified; out of these, 5 mutations located at Nsp2, Nsp3, Nsp14, and ORF10 genes occurred with a <0.1% frequency in the global dataset. On the basis of mutation profiles, five genomes were clustered into two sublineages (B.1.617.2 and AY.31) or subclades (21A and 21I). The phylogenetic analysis of viral genomes from several regions of China and Myanmar revealed that five patients had different viral transmission chains. Taken together, we established a nanopore sequencing platform for genetic surveillance of SARS-CoV-2 and identified the variants circulating in Zhengzhou during August 2021. Our study provided crucial support for government policymaking and prevention and control of COVID-19.
