How does African classical swine fever spread?

I believe that no matter whether they are farmers or urban people, they should be completely familiar with the word African classical swine fever recently. Since the emergence of African classical swine fever in China, everyone has been in a panic. It was thought that only one area appeared, but another province was found after a while. So how does African classical swine fever spread?

I. Communication by means of transport

All kinds of vehicles passing through the epidemic areas, loading and transporting sick pigs and their products, once the disinfection is not strict and not thorough, it will become the source of transmission of classical swine fever in Africa. As long as these means of transport, wherever they go, they will spread, which is an important way for the spread of classical swine fever in Africa.

II. Communication between people

All pigs and pork products that have come into contact with African classical swine fever are very likely to spread the epidemic, such as the virus hiding in hair, hats, clothes, shoes and socks, hanging bags, body skin, and so on. Spread African classical swine fever.

III. Spread of pig products, etc.

Live pigs and pig products are the main ways to spread African classical swine fever. If the major pig farmers have a recessive source of infection, there will be pigs with disease and pork missed inspection and enter the market, resulting in pigs and pigs, pigs and farmers, pork and markets, pork and farmers, pork and consumers, reciprocating crossover, overlapping measures, from near to far, from point to surface, from line to surface, mutual transmission and infection, resulting in an increase in ways of transmission and acceleration of transmission.

IV. Spread of pig feed

After diseased pork products enter the market, consumers bring pork into restaurants and hotels and into the kitchens of thousands of households, and the kitchen waste oil and water produced are usually lost to rural farmers as raw feed for pigs, resulting in a pandemic of African epidemics. At present, this is the most important way for the spread of classical swine fever, and it is the source of transmission that can not be ignored.

V. Natural biological transmission

Because the wastes such as pig feces in rural areas are not properly managed, disinfection and sterilization are not thorough and strict, all kinds of insects, birds and other small animals carry germs and viruses from diseased pig feces and fly to other places or farmers and feeds to spread the epidemic. In addition, the spread of wastes such as pig manure with disease expands with natural factors such as wind and torrential rain, leading to the rapid spread of the disease.
