African Swine Fever (ASF) and Classical Swine Fever (CSF) are two different diseases with different modes of infection, pathogens and symptoms.
Pathogens:
African swine fever (ASF) is a highly contagious disease caused by the African swine fever virus. This virus poses a great threat to pig herds, and there is currently no effective vaccine. ASF virus is mainly transmitted through wild pigs and molluscs, but can also be transmitted to domestic pigs.
Classical swine fever (CSF) is a highly contagious disease caused by swine fever virus that infects pigs. There are currently vaccines available for prevention.
Propagation mode:
African swine fever (ASF) is mainly transmitted through direct or indirect contact with infected pigs, or indirectly through infected wild animals (such as wild boars). Additionally, ASF viruses can be transmitted in meat or other swine products.
Classic swine fever (CSF) is mainly transmitted through direct contact with nasal mucus, saliva, feces and diseased tissue, and can also be transmitted through the air.
symptom:
After being infected with African swine fever (ASF), pigs develop symptoms such as fever, loss of appetite, shortness of breath, and red and purple spots on the skin. Extremely severe cases result in high mortality.
After swine fever (CSF) infection, pigs develop symptoms such as high fever, loss of appetite, listlessness, shortness of breath, vomiting, diarrhea, skin, and infectious skin lesions. The mortality rate of young pigs is high.
In terms of prevention and control, the prevention and control of African swine fever and swine fever require strict biosecurity measures, including isolation of sick pigs, cleaning and sanitation, and strengthening quarantine. It is worth noting that African swine fever poses a greater threat to pigs because there is currently no effective vaccine for pigs.
