The novel coronavirus is an RNA virus, which has a relatively simple structure of a protein wrapped around a segment of ribonucleic acid. The novel coronavirus itself does not have the ability to proliferate, and after parasitizing in human cells, it relies on intracellular materials and enzymes to reproduce and multiply. When the novel coronavirus is detached from human cells, it is actually very susceptible to environmental factors, such as high temperatures, the structure of the virus will be destroyed and cannot survive. Under ultraviolet light, the virus will also undergo cleavage and will be destroyed. Therefore, the new coronavirus is afraid of ultraviolet light and high temperature. If the effect is sustained for a certain period of time through UV irradiation or high temperature, both will kill the novel coronavirus. Source: Dr. Yurai
