African swine fever is an acute, hemorrhagic and severe infectious disease caused by African swine fever virus in pigs. It is characterized by high fever, severe bleeding of internal organs and high mortality. African swine fever is not a zoonotic disease and the related viruses will not infect humans, but food, shoes, tools, vehicles, etc. contaminated by the virus may contribute to the spread of the virus. This virus can survive for a long time under non-high temperature conditions, and there is currently no animal vaccine or specific drug that can prevent it.
