Initiation of new outbreaks starts by feeding infected uncooked pork scraps.

Symptoms are very similar to FMD and include: Mortality is low, but there may be some deaths in suckling piglets.

The capsid surface structure reveals a regular pattern with distinctive features.

The genome is not segmented and contains a single molecule of linear positive-sense, single-stranded RNA.
