“African swine fever and classical swine fever are two completely different diseases in their epidemiology and the behaviour of the virus” How does the African swine fever virus reach and infect domestic pigs? The most common routes are spelled out in this podcast featuring Dr. Klaus Depner, a virologist and ASF specialist who leads a working group on transboundary animal disease management at FLI, the German federal institute for animal health. The virus does not enter on infected droplets or airborne transmission, he says, most often it has been carried into the barn by people. The main way it invades a pig's body is through contaminated feed or water, although even then only a small proportion of the animals exposed become infected.
