Neocoronaviruses can survive in air for less than 3 hours, depending on temperature, humidity, attachment to surfaces, and formation of aerosols. Neocoronaviruses do not survive for long periods of time after being removed from their hosts and usually survive in air for less than 3 hours. When the ambient temperature is low and the air humidity is high, the survival time of the new coronavirus is relatively longer, and vice versa. If the virus adheres to surfaces, the survival time can be extended to tens of hours, and even longer on smooth surfaces, such as metal and glass. If the neocoronavirus forms an aerosol in the air, the survival time can be extended to about 3 hours. In addition to wearing a good mask, you should wash your hands frequently and ventilate your home to prevent infection by the new coronavirus.
