Epidemic prevention and control

New Coronavirus belongs to β Coronavirus of genus, with envelope, round or oval particles, often pleomorphic, with a diameter of 60-140 nm. Its gene characteristics are significantly different from those of SARS r CoV and mersr cov. The present research shows that the homology of SARS bat- coronavirus (bat- SL-CoVZC45) is more than 85%. When isolated and cultured in vitro, 2019-nCoV can be found in human respiratory epithelial cells for about 96 hours, while in Vero E6 and Huh-7 cell lines, isolation and culture take about 6 days.

The understanding of the physical and chemical characteristics of coronavirus mostly comes from the study of SARS CoV and mers cov. The virus is sensitive to ultraviolet and heat. Lipid solvents such as 56 ℃ for 30 minutes, ether, 75% ethanol, chlorine disinfectant, peracetic acid and chloroform can effectively inactivate the virus, but chlorhexidine can not effectively inactivate the virus.
