Study team explored sampling options to identify a reliable and logistically more feasible protocol during a large equine herpesvirus-1 outbreak.

The EI outbreak has claimed the lives of 129 horses to date, and officials at the BLM holding facility in Colorado say the results of culture and microscopic examination indicate a multifactorial respiratory disease complex.

The second of the FEI’s three-part report into the 2021 outbreak of the neurological form of Equine Herpes Virus (EHV-1) in mainland Europe looks at Return To Competition protocols and the EHV-1 By-Laws and sanctioning system incorporated into the FEI Veterinary Regulations.

For Colorado State University student Caroline Wollman, the threat of equine herpes virus type 1 got personal when her horse Cody was infected last year.

The new VSS app uses artificial intelligence to pick up any flags on disease trends or syndromes that might go with a disease.

Researchers find the virus can replicate in the respiratory tract, with horses developing antibodies after exposure.

Nine deaths were reported, as well as abortions. The authors want more extensive seroprevalence studies on EHV-4 in the country.

Britain’s National Equine Forum has celebrated its 30th birthday, and this year looked at grave threats to sustainability within the equestrian sector, from workforce challenges to growing resistance to de-wormers.

The mosquito-borne virus can infect horses, pigs, and humans, and has been confirmed in Victoria, New South Wales, Queensland, and South Australia.

EHV-1 was found in tissue samples taken from all 43 aborted fetuses, researchers report.

The first of a three-part report into last year’s EHV-1 outbreak in Europe evaluates what was done correctly and identifies where there were failings, and lessons learned.

Horses are susceptible to subclinical infections, scientists in California report following analysis of samples from more than 1200 horses.

Researchers say more active surveillance will be required to keep watch on the virus, which can infect horses and humans.

The virus is closely related to far more dangerous insect-borne viruses such as African horse sickness and blue tongue.
