KEY FACTS

Disease Classification

This disease is caused by a complex and large DNA virus in the
Asfarviridae Family. It was first classified in Africa in 1921 and has been spreading within Europe and Asia recently. ASF is not a zoonosis (cannot spread from animals to people).

Transmission

There are various cycles of infection in different regions of the world. The general routes of entry onto a farm for the virus are: 1. Direct – contact of healthy animals with infected wild boar or domestic pigs 2. Indirect – contact of healthy animals with infected blood, meat and food products. Vectors such as soft ticks play a role in some transmission cycles. Fomites such as vehicles and clothing can also be a means of transmitting the virus.

Vaccine

There is currently no effective vaccine for ASF, although various inactivated, live and subunit vaccine approaches have been investigated. Research is ongoing around the world to find a safe and efficacious vaccine.

Clinical Signs

Treatment

There is no specific treatment to cure animals with ASF.

Management

The virus is very resistant in the environment and without an effective vaccine the management of the disease currently focusses on preventing outbreaks through good biosecurity. Double fencing and quarantine help prevent direct spread, whilst cleaning and disinfection of vehicles plus changing clothing for farm visitors help prevent indirect spread. It is essential to stop naïve animals contacting any kind of food that may contain pork products, so all human food must be disposed of appropriately. Kitchen scraps must not be fed to pigs and all tourists/travellers must adhere to advice regarding carrying certain foods whilst travelling. Raising awareness of the disease at all levels is important.
