I think this is really good article from the Equiery: https://equiery.com/quarantine-at-wyndham-oaks-lessons-from-a-strangles-outbreak/
And I really applaud Wyndham Oaks for sharing their experience and how they managed and tested for strangles and also spreading the knowledge that some horses can be asymptomatic carriers of strangles.
I had a lease a couple of years ago at a private barn. At one point the owner bought some horses from a feedlot. She quarantined the feedlot horses for 60 days - way more than a lot of people do! A month after the quarantine ended I pulled my lease out of the field and he had thick green discharge from coming out of his nose and a temperature. The next day, he and another horse had abscesses under their jaws. None of the feedlot horses ever showed symptoms.
My lease got the worst of it, actual bastard strangles and and abscesses going up and down his chest. He had a seizure at one point, but somehow he eventually recovered and he’s still with us (and now that his kid has graduated college and back in the area, she’s working on legging him back up and getting her seat back).
I cannot imagine dealing with strangles at a large boarding barn.
