The survival time of the rabies virus when exposed to air is affected by the temperature and humidity of the environment and is not clearly defined; it is generally inactivated after about 2 minutes of exposure to air. If the rabies virus is exposed to dry, hot environments, such as daily sunlight and ultraviolet light, it is inactivated in about half an hour. If it is exposed to ultraviolet light in a laboratory, it can be inactivated in a few minutes. Similarly, the rabies virus can survive for less than two minutes in a hot environment of about 100 degrees Celsius. However, if the rabies virus is in a humid and warm environment, the virus activity is not easily destroyed and it can survive for a longer period of time. Therefore, as long as you are not bitten or scratched by animals in your daily life, you do not need to worry too much about being infected by the rabies virus.
