SYMPTOMS

• AHSV fever is a seasonal, viscerotropic disease characterized by subcutaneous/pleural edema and fever. The virus is manifested in several forms: peracute, subacute, acute, and horse sickness. Often, the associated respiratory and circulatory distress results in severe disease and death. Severity of disease varies among species, with horses being the most affected, followed in order by mules, donkeys, and zebras.
