How Many Days After African Swine Fever Onset Do Sows Die

African swine fever is a virulent infectious disease with high fever, high resistance and a high mortality rate. Once infected, the mortality rate can reach as high as 100%, and there is currently no drug that can treat it. Many people do not know how long it takes for a pig to die after contracting African swine fever. Here is a detailed explanation.

Because sows generally have weaker disease resistance, accumulated toxins, poorer physical condition and their own bodily depletion, they are relatively more susceptible to African swine fever infection.

A pig that contracts African swine fever generally dies within 10-15 days, and some pigs even die within 1 to 2 days of developing a fever. Prevention work against African swine fever must be done well to avoid spreading it to more pigs. Pig farms need to strictly control the entry and exit of farm workers, transport vehicles and susceptible animals. Strict disinfection should be carried out when entering and leaving the pig farm to avoid carrying the virus and causing an outbreak on the farm. At the same time, food scraps and swill must not be used to feed pigs, as this makes them prone to African swine fever. If an African swine fever outbreak does occur, all pigs must be culled and deeply buried in a timely manner; this is currently the only prevention and control measure.

Global incidence situation

This disease was first reported in Kenya in 1909 and has always existed in sub-Saharan African countries. In 1957 it spread successively to Western European and Latin American countries, most of which culled it in a timely manner, but it is still prevalent in Portugal, southwestern Spain and Sardinia, Italy.

Since 2007, African swine fever has occurred, spread and become prevalent in many countries around the world, especially in Russia and its surrounding areas. In March 2017, an African swine fever outbreak occurred in Irkutsk Oblast in the Russian Far East. The outbreak site was relatively close to our country, only about 1000km away; on April 12, 2017, our country's Ministry of Agriculture issued an emergency notice on further strengthening the risk prevention work for African swine fever.
