cord-285403-h8ahn8fw	Zhang, Liangsheng	Origin and Evolution of the 2019 Novel Coronavirus	2020-02-03		.txt	text/plain	830	48	57	To the Editor-The 2019 novel coronavirus disease (2019-nCoV or COVID-19) recently reported from Wuhan (China), which has cases in Thailand, Japan, South Korea, and the United States, has been confirmed as a new coronavirus [1] . Based on our phylogenomic analysis of the recently released genomic data of 2019-nCoV, we showed that the 2019-nCoV is most closely related to 2 severe acute respiratory syndrome (SARS)-like CoV sequences that were isolated in bats during 2015 to 2017 [2] , suggesting that the bats' CoV and the human 2019-nCoV share a recent common ancestor ( Figure 1A) . This market also sells wild animals or mammals, which were likely intermediate hosts of 2019-nCoV, which originated from bat hosts ( Figure 1B ). The 2019-nCoVs have long branches (0.09) for the 2 isolated in the phylogenomic tree ( Figure 1A) , indicating that the 2019-nCoVs likely share bat hosts. There were 3 genotypes present in samples from Guangdong province, indicating that the 6 strains were infected from different places in Wuhan.	./cache/cord-285403-h8ahn8fw.txt	./txt/cord-285403-h8ahn8fw.txt
