2. What are the main routes of transmission of African classical swine fever?

The source of African classical swine fever may be related to infected pig products in airports, ports and other import channels that have not been processed at high temperature, and their tissues, organs, secretions, feces, and blood contain viruses, which can pollute pig houses, utensils, bedding, feed, vehicles, and so on. Healthy pigs are mainly infected by contact with diseased pigs and contaminated feed, drinking water and kitchen leftovers. In addition, other insects such as soft ticks carrying African classical swine fever can also spread African classical swine fever virus by biting healthy pigs.

At present, there is no effective drug to treat, and there is no related vaccine to prevent it. Only by strengthening the supervision and testing of pigs, strict closed management of pig-raising places, disinfection and isolation of pig houses. In order to prevent sick pigs from infecting healthy pigs, once the epidemic is found, it is necessary to block, isolate, cull, disinfect and harmlessly dispose the diseased pigs, so as to prevent the spread of the epidemic from affecting other healthy pigs.
