My sister's horse barn (where she boards her horse) has just been quarantined because one of the horses was diagnosed with Strangles. This disease cannot effect humans but it be very easily spread from horse to horse. This disease can be fatal. Our horse is not showing any signs or symptoms, but is there anything I can do to HELP prevent him from getting it? The horses are separated, but it is still extremely likely that he can get it. Please answer, and tips or suggestions? Please answer ASAP! thanks.
