The new coronavirus is intolerant to heat and the optimal temperature is about 4°C. If heated to 56°C, this coronavirus can be completely killed in 30 minutes. Therefore, in dealing with coronavirus, clothing can be boiled or scalded by high temperature, or a clean environment with repeated use of the mask, or by steaming. For example, boiling in water for about 15 minutes in an airtight bottle can kill coronavirus. It is also intolerant to ultraviolet light. Generally, killing it with ultraviolet light means that it can be killed in the clinic or by a special ultraviolet light in ten minutes. However, UV rays from the sun are not strong enough to kill coronavirus. For example, it is less likely to kill coronavirus by sunbathing, especially now that it is cooler and less sunny.
