“We learned that it's a human-made disease so it's a matter of what people are doing and how they behave” Virologist Dr. Klaus Depner in Germany tells us that preventing the entry of the African swine fever virus is fundamentally a matter of good farm biosecurity coupled with education of the general public so they are not transmitting the virus or carrying it in food or other materials. At the German federal institute for animal health FLI, Dr. Depner heads a working group on transboundary animal disease management. Controlling ASF within territories demands a long view, he says. African swine fever is a disease where you need lots of patience.
