Sunbathing can prevent the new coronavirus. Epidemiological studies have confirmed that the new coronavirus is sensitive to ultraviolet light, so bedding, pillows, clothing, towels, etc. can be disinfected by sunlight for 5-6 hours at home. At the same time, indoor disinfection can also be done by UV light for about 30 minutes a day. In addition, the new coronavirus is sensitive to heat and can be inactivated in about 30 minutes at 56°C. Lipid solvents such as ether, 75% ethanol, chlorinated disinfectants, peroxyacetic acid and chloroform can effectively inactivate novel coronaviruses.
