😷Equine Herpes Virus (EHV)😷
With the EHV-1 outbreak south of the boarder, we have been getting a lot of questions about EHV, so wanted to make a post to address some frequently asked questions!
😷What's going on?
Equine Herpes Virus outbreaks are common. This outbreak made news because the outbreak occurred at a very large horse show in Texas, causing spreading of the outbreak as horses returned home. EHV can also mutate (transform) into a more serious and deadly form called EHM, which is what happened in this case.
😷Where can I get more information about EHV/EHM?
We have a fact-sheet on our website that lays out basic, factual information about this virus. You can follow this link to find it on our website!

😷What do I need to do to protect my herd?
Horses with any contact with this outbreak should be on strict quarantine - if you are planning to have your horse near a horse that just came back from the USA, double check that it's not from an infected barn or show (the USA is very large - most places are safe!). As always, we recommend good biosecurity (don't let your horse touch other horses, don't allow people to touch your horse, don't touch other horses). As always, we also recommend vaccinating for EHV every 6 months if you are showing/exposing your horse to other horses year-round.
