The cure for distemper

"Equine distemper" is actually infection with Streptococcus equi which causes Strangles. Prevention of Strangles involves minimizing contact with horses or items that have been in contact with horses that have Strangles, have been exposed to Strangles or have recovered from Strangles recently. Quarantine of horses coming into a facility also helps to prevent Strangles by allowing time to ensure that the new horse is disease free before exposing horses to it. Cleaning and disinfecting all buckets, feeders, bridles, etc prior to sharing them between horses is another way to reduce the spread of disease. There are vaccines against Strangles as well, but they are not highly effective and have higher risk of adverse reactions associated with them so they are only recommended for horses in situations where there is a high risk of exposure to Strangles.
