The new coronavirus can survive in the human body and living organisms, and when it leaves the human body the survival time will be very short, and it will be inactivated very soon. The new coronavirus will be inactivated at 56℃ for 30 minutes because the temperature of cooking will be very high, and the higher the temperature, the shorter the survival time will be. Generally, no new coronavirus will survive after cooking, so diet will not transmit new coronavirus. At present, the new coronavirus is mainly transmitted by close contact and droplet transmission, the source of infection is mainly diagnosed patients, suspected patients and patients in the incubation period, and do a good job to go out less, less contact with outsiders, avoiding gatherings and other ways to effectively prevent the new coronavirus.
