Real-time tracking of prevalence of MERS-CoV from 2012-2019
Sequence analysis reveals 2 conserved pyrimidine nucleotides in the loop of stem loop 2 of MERS-CoV 5’-UTR. According to this newly identified genetic signature, MERS-CoV can be re-genotyped into 3 types, U—-U, C—-U, and C—-C types. The prevalence of each virus type during 2012 to 2019 was determined by plotting the numbers of case reported in NCBI GenBank. The genetic drift between human and camel viruses was compared.
