FAQ
Frequently Asked Questions
No, classical and African swine fever are not zoonotic; they do not infect humans. They pose a threat only to pigs and the agricultural economy.
No. While the virus is not a direct human health threat, infected animals are destroyed, and meat from them does not enter the food chain due to animal welfare and disease control laws.
They are caused by different viruses. Classical Swine Fever (CSF) is caused by a pestivirus, while African Swine Fever (ASF) is caused by a large DNA virus (Asfarviridae). Both are severe, but ASF is often more lethal and has no vaccine.
It spreads through direct contact with infected pigs, their bodily fluids, or contaminated feed, equipment, and clothing. It can also be spread by soft ticks (ASF) and via improperly processed pork products.
