Re: West Nile Virus

The only way to boost specifically for WNV is by vaccination **but** there is a good chance the other horses were already naturally infected and in that case should be immune.  Most infections are asymptomatic or so mild (e.g. fever only) they are missed. I would run titers.

When faced with an imminent threat of infectious disease I recommend levamisole, 1 to 2 mg/kg, 3 to 4 days on and 3 to 4 days off.
