Early detection and understanding sources of pseudorabies virus (PRV) are essential to contain spread and prevent economic losses, should the virus arrive in the US.

There are two categories of pseudorabies virus (PRV). Classical PRV was formerly present in North American commercial production prior to eradication in 2004. It has been eliminated in much of the developed world, but does reside in feral pigs in the US, Europe, Latin America, and Asia.

In May 2017, the Swine Health Information Center (SHIC) released information from a study it funded showing the potential for viruses to contaminate and survive in feed ingredients.

Senecavirus A (SVA or Seneca Valley Virus) infection is indistinguishable from foot-and-mouth disease (FMD) and other swine vesicular disease, so every outbreak, including at harvesting plants, must be investigated.

While Japanese encephalitis virus (JEV) is endemic in Asia and the Pacific, many countries like the United States don’t have and don’t want this disease.
