Swine fever is an acute, contagious disease of pigs, characterized by high fever, severe bleeding from internal organs, and high mortality rate, but it does not pose a direct threat to humans.
Under natural conditions, only pigs are infected, and pigs and wild boars of different ages, genders, and breeds are susceptible, which can occur all year round. Infected pigs are the main source of infection. The excrement and secretions of infected pigs, as well as the blood, meat, internal organs, wastewater, and waste contaminated feed and drinking water from dead pigs, organs, corpses, and slaughtered pigs, can spread the virus. The transmission of swine fever is mainly through contact and infection through the digestive tract. In addition, sows infected with diseases and weak strains can also vertically infect fetuses through the placenta, resulting in weak piglets, stillbirths, mummified fetuses, etc.
