African Horse Sickness is a viral disease that primarily affects horses, donkeys, and mules. It is caused by the African Horse Sickness Virus, which is transmitted by biting midges, particularly the species Culicoides. The disease can lead to severe respiratory and cardiovascular issues, and it is often fatal if not treated promptly. Symptoms of African Horse Sickness include fever, swelling around the eyes and face, and difficulty breathing. There are different forms of the disease, ranging from mild to severe. Vaccination is available and is the most effective way to prevent outbreaks, especially in regions where the disease is common.
