The novel coronavirus is afraid of heat. Current research has found that novel coronaviruses are sensitive to heat, in which 30 minutes at 56°C and 5 minutes at 100°C can effectively kill novel coronaviruses. In addition, ester solvents such as ether, 75% ethanol, chlorine disinfectants, peracetic acid and chloroform can effectively inactivate the novel coronavirus. The source of infection of the new coronavirus is mainly the new coronavirus infected people, which is infectious during the incubation period, and is more infectious within 5 days after the onset of illness. Since the new coronavirus mainly infects the mucous membranes of the respiratory tract and lung tissues, high temperatures, alcohol consumption, and various types of medications are generally unable to inactivate the virus inside the cells. In order to avoid the difficulty of treatment caused by infection, the best way is to get vaccinated in time, and do a good job of preventive measures in daily life, pay attention to personal hygiene to minimize the risk of infection.
