Epizootic Hemorrhagic Diseases (EHD) are a group of viral diseases primarily affecting wild and domestic ruminants. The causative agents, belonging to the Orbivirus genus within the Reoviridae family, are transmitted by biting midges of the Culicoides species. EHD viruses can cause mild to severe clinical manifestations, including fever, nasal discharge, and hemorrhagic lesions. The disease is characterized by sudden onset, and outbreaks can result in high morbidity and mortality rates among infected animals. While cattle, deer, and sheep are susceptible, some species exhibit resistance. EHD outbreaks have a significant economic impact on livestock industries due to decreased productivity, trade restrictions, and costs associated with disease control measures. Vaccination and vector control are essential strategies to manage EHD, although challenges remain in developing universally effective vaccines and controlling the spread of Culicoides vectors.
