COVID-19 presents varied symptomatic features [2] , [3] , [4] , [5] , [6] , [7] with a wide range of incubation periods and epidemic curves J o u r n a l P r e -p r o o f 4 are occurring [21] , [22] , the pathogenicity and origins of the mutated substrains of SARS-CoV-2 should be available in real time to adopt early measures by authorities at the onset of emergence. We examined the nucleotide mutations and visualized the transmission trajectories of SARS-CoV-2 by consulting the world specimens registered in the virus data bank of the National Center for Biotechnology Information (NCBI) [32] . Collectively, the annotations in the virus genome database are of fundamental use to hypothesize the pathogenicity and to trace the transmission route at the early phase of emergence of the new substrains.	./cache/cord-331155-jkm4fuw4.txt	./txt/cord-331155-jkm4fuw4.txt
