The maximum survival time on a surface is mainly related to the environment and surface material, and may be as long as several years or as short as a few hours.
1. Environment: The survival time of the new crown virus on the surface of the object is related to the temperature and humidity of the environment. The lower the surface temperature of the object, the longer the survival time of the new coronavirus. At temperatures as low as -60°C, neocoronaviruses can even survive for several years.
At temperatures around 37°C, the survival time of new coronaviruses is relatively short and may be in the range of a few hours. At stable temperatures with a relative humidity of about 50%, neocoronaviruses survive for a shorter period of time.
2. Surface material: relevant studies have shown that the survival time of the new crown virus is different on the surface of different objects, such as copper surface survival time of about four hours, cardboard surface can survive for about 24 hours, stainless steel surface can survive for two days and so on.
In addition to surviving on the surface of objects, the new crown virus can also survive in the air through droplets, so it is recommended to go out and wear a good mask, which can to a certain extent avoid infection with the new crown virus.
