Wuhan coronavirus infection is the new emerging coronavirus infection caused by the 2019 novel coronavirus (2019 n-CoV). The 2019 n-CoV wasfirstly isolated, sequenced, and recorded from China. After thefirst discovery of 2019 n-CoV infection, more cases are observed in China as well as in other countries. The disease was detected and molecularly confirmed in several countries (such as the USA and Australia). The accelerating increased number of infected cases leads to the WHO declaration on global emergence regarding this new disease.
Here, the authors performed comparative genomics analysis on public available complete genomes of 2019 n-CoV recorded in the 1st month of outbreak (December 2019–January 2020). Overall, ten available complete genomes in PubMed were processed by BLAST tool for multiple alignments (https://blast.ncbi.nlm.nih.gov/BlastAlign.cgi). The studied genomes include MN988668.1 (thefirst referencing genome), MN997409.1, MN988669.1, MN994468.1, MN994467.1, MN985325.1, MN988713.1, MN975262.1, MN938384.1, and MT007544.1. According to the analysis, the similarity ranges from 99.96% to 100% (average = 99.983% +0.012%). The variation, which implies mutation, is 0%–0.04% within the 1st month period of outbreak. Therefore, the mutation of the new 2019 n-CoV already occurs. Further monitoring on progress of mutation is recommended for early detection of possible emerging serious variant of the virus.
