African Horse Sickness AHS Vaccine

SIGNS OF AFRICAN HORSE SICKNESS

African Horse Sickness is primarily characterized by fever, edema of the lungs and subcutaneous tissues as well as widespread hemorrhage.

The pulmonary form is a peracute infection, with clinical signs being fever, congestion, dyspnea, and death due to severe pulmonary edema.

The cardiac form is characterized by subcutaneous edema and consequent swelling of the supraorbital fossae of the horse, giving the appearance of a swollen head.

The acute, or mixed, form is a mixture of the pulmonary and cardiac forms. Both lung involvement as well as the externally visible subcutaneous edema and supraorbital swelling is normally seen.

Mortality may reach 90% in epidemics.
