Likelihood-mapping analysis of "dataset_14" revealed that 100% of the quartets were distributed in the center of the triangle, indicating a strong star-like topology signal reflecting a novel virus, which may be due to exponential epidemic spread ( Figure 1A) . Of note, the strong star-like signal (100% of quartets were distributed in the center of the triangle) from "dataset_14" at the beginning of the virus outbreak suggests that 2019-nCoV initially exhibited low genetic divergence, with recent and rapid human-tohuman transmission. ./cache/cord-298902-afek8kgr.txt ./txt/cord-298902-afek8kgr.txt
