Classical swine fever, commonly known as "rotten intestinal plague", is an acute, febrile and contact infectious disease caused by flaviviridae classical swine fever virus. It is highly contagious and deadly. This disease only infects pigs under natural conditions and has no effect on human body. Even if you buy food with swine fever virus, you won't get swine fever. Because the antigen of classical swine fever virus is only aimed at the antibody of classical swine fever virus, it can only combine with the antibody in pigs, and there is no antibody of this virus in humans, so there is no need to worry about contracting classical swine fever.
