The survival time of the rabies virus after leaving the body is greatly affected by the environment. It can usually survive for about an hour in a dark and humid environment, and can die in a few minutes when it is hot and dry at 100 degrees Celsius, and can survive for several years if it is minus 70 degrees Celsius or lyophilized and stored in an environment at 4 degrees Celsius. The survival time of rabies virus after leaving the body is related to the environmental temperature, humidity, light and other conditions. If the ambient temperature and humidity are suitable for the rabies virus to survive, such as in a dark and humid environment, the rabies virus may survive for tens of minutes to about an hour. If the rabies virus is stored at -70 degrees Fahrenheit or lyophilized and stored at 4 degrees Celsius, the rabies virus can survive for several years. If the ambient temperature is high, the light is sufficient and the air is dry, the rabies virus may survive for a much shorter period of time, such as tens of minutes. If the temperature reaches 100 degrees Celsius, it may even die within minutes. Rabies viruses are sensitive to chemical disinfectants, such as antiseptic solutions. In general the rabies virus is not very resistant to the external environment and can be quickly inactivated by acid or alkaline solutions. If you are bitten or scratched by a dog, cat or wild animal, it is recommended that you consult your local healthcare provider and get a rabies vaccination if necessary to prevent the rabies virus.
