What are the characteristics of the new coronavirus

The novel coronavirus belongs to the new coronavirus of the genus β, with envelope, round or oval particles, often polymorphic, with a diameter of 60 ~ 140nm. The genetic characteristics of SARSr-CoV and MERSr-CoV were significantly different. Current studies have shown that homology with bat SARS-like coronavirus (BAT-SL-CovZC45) is more than 85%. When isolated and cultured in vitro, 2019-NCoVwas found in human respiratory epithelial cells in about 96 hours, while it took about 6 days to isolate and culture in VeroE6 and Huh-7 cell lines.

The understanding of physical and chemical characteristics of coronaviruses is mainly from the study of SARS-CoV and MERS-CoV. The virus is sensitive to ultraviolet light and heat, and lipid solvents such as ether, 75% ethanol, chlorine-containing disinfectant, peracetic acid and chloroform can effectively inactivate the virus, while chlorhexidine can not effectively inactivate the virus.
