Neocoronaviruses can be kept in the refrigerator for a few days to a few months, depending on the temperature inside the refrigerator. Neocollins are generally more likely to survive for long periods of time in a humid environment. If the temperature inside the refrigerator is around 10 to 15 degrees Celsius, the virus can generally survive for about 3 to 5 days. If the temperature inside the refrigerator is around 0 degrees Celsius, the virus can generally survive for about two weeks, and for some refrigerators with strong refrigeration effect, the temperature can reach minus 20 degrees Celsius, at which time the virus can survive for a few months at the longest. New coronavirus may appear on vegetables and various objects after refrigeration, so be careful to sterilize the items after purchasing them for long-distance refrigeration transport to avoid spreading the virus. If you develop symptoms of the virus, you should seek medical attention immediately to avoid aggravation of the condition and spread of the disease.
