Vaccination is available. It does not guarantee protection against the virus but usually limits the duration and severity of the disease.
Vaccination of non-infected horses may be worthwhile to restrict the spread.
Horses recovering horses can be carriers and still harbour Strep. equi without any symptoms. Consequently, new or recurrent outbreaks are likely. Aggressive quarantine measures should be used.
