African swine fever is an acute, hot and contact infectious disease caused by swine fever virus. Acute cases showed septicemia changes; Chronic cases mainly occur in the large intestine, especially near the ileocecum. Therefore, the disease is also called "rotten intestinal plague". Regardless of age, sex, weight and season, once one of the pigs gets sick, it will spread rapidly in the whole group and the mortality rate is very high. The average incubation period is 7 days.
In theory, it is possible to continue raising pigs. African swine fever epidemic areas can be removed after 42 days of testing without problems, which means that African swine fever can be completely eliminated. Then pig farms infected with African swine fever can raise pigs after 42 days. At the same time, the use of barracuda to avoid horse plague can greatly reduce the incidence and increase the slaughter.
