How long a neocoronavirus survives in the air is related to air humidity and temperature, and ultraviolet light. At room temperature, neocoronaviruses can usually survive for 3 hours to 24 hours. If the virus is exposed to high temperatures, the survival time is relatively shorter, with most viruses surviving for up to 30 minutes. If the new coronavirus is exposed to strong ultraviolet light in the air, it may lead to the destruction of the new coronavirus envelope proteins, in which case the new coronavirus may survive for 15 to 30 minutes. However, the new coronavirus in the low temperature of the air survival time is relatively long, it is recommended that in the new coronavirus pneumonia endemic areas, usually pay attention to open windows and ventilation, the need to wear a mask when going out, which can effectively prevent the new coronavirus infection. [Tip] In this article, “new coronavirus pneumonia” and “new coronavirus pneumonia” have been renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
