Influenza virus has weak resistance and is not heat-resistant. The virus can be inactivated at 56℃ for 30 minutes. The infectivity is quickly lost at room temperature, but it can survive for several weeks at 0°C to 4°C, and can survive for a long time below -70°C or after freeze-drying. Viruses are also sensitive to dryness, sunlight, ultraviolet rays, and chemicals such as ether, formaldehyde, and lactic acid.

The main source of influenza virus infection is patients, followed by latent infections. Infected animals may also be a source of infection. The main route of transmission is droplets containing influenza viruses entering the body through the respiratory tract. A small number of people can also be infected through indirect contact with handkerchiefs, towels, etc.
