Equine hepatitis virus (EqHV)

Test code: S0233 - Ultrasensitive qualitative detection of equine hepatitis virus (EqHV) by reverse transcription real time PCR.


Equine hepatitis virus (EqHV) or equine hepacivirus is a non-primate hepacivirus (NPHV), phylogenetically related to the human hepatitis C virus. EqHV is a single-stranded RNA virus containing an approximate 9.2 kb genome.

Horses have been infected with this virus in the United States, Japan, New Zealand, and Europe. EqHV can cause subclinical disease in adult horses with transient mild elevations in liver-derived serum enzymes. Similar to EqPV-H, EqHV can be found in healthy carriers with no clinical signs, which may serve as reservoirs for infection of other horses.

Transmission of EqHV is usually through veterinary products, such as vaccines, immune sera, or other equinederived blood products. In an attempt to eliminate the risk of equine serum hepatitis secondary to equine biologic product administration, the USDA Center for Veterinary Biologics has proposed that all licensed equine blood products be tested for EqPV-H and EqHV.

Serological detection of the virus is not very sensitive and is mainly used to identify horses who may have had prior exposure to the virus. Detection by viral culture is also not very sensitive, and is slow. Effective detection of active carriers of the virus relies on the use of molecular detection by polymerase chain reaction, which is rapid and specific (Tanaka et al., 2014).


  • Help confirm the disease causing agent
  • Shorten the time required to confirm a clinical diagnosis of the presence of these viruses
  • Help ensure that horse populations are free of these viruses
  • Early prevention of spread of these viruses
  • Minimize human exposure to these viruses
  • Safety monitoring of biological products that derive from horses
