One: Novel coronaviruses are intolerant of high temperatures
With better understanding, experts have found that novel coronaviruses do not tolerate high temperatures. They survive well at low temperatures, but, as the temperature increases, their activity slowly decreases. When the temperature reaches 56 degrees or higher, they basically lose their activity and lose their infectivity. When the high temperature lasts for about half an hour, they are completely killed. Therefore, we must cook the food thoroughly before eating it when we do eat it.
Two: Novel coronavirus is not resistant to high levels of alcohol
In the process of fighting the new coronavirus, experts found that: the new coronavirus is not resistant to alcohol, and it is quickly killed in a certain concentration of alcohol and loses its infectivity. However, the concentration of alcohol should be more than 75%, which means that it should reach medical grade.
Besides alcohol, disinfectants containing chlorine can also kill novel coronavirus.
III: Novel coronavirus is not resistant to ultraviolet light
In our daily life, ultraviolet light is a common disinfection method. UV light is effective against many viruses, and it is also effective against the novel coronavirus. Putting the new coronavirus under UV light for 10 minutes will kill it cleanly.
Fourth: the survival time in the air is relatively short
It was found that the new coronavirus can only survive in the air for about 2 hours after leaving the host. Many people may think: 2 hours is still short ah? We can't look at the absolute value, we have to look at the relative value. Compared to other infectious viruses, the airborne survival time of novel coronaviruses is relatively short, like influenza A, which survives up to 24 hours in the air.
