The enzootic nasal tumor of sheep and goats is a progressive and contagious disease caused by enzootic nasal tumor virus. It is mainly characterized by tumor growth in the mucosal epithelial tissue of the ethmoid bone and nasal turbinates within the nasal cavity of sheep and goats. In the later stage of the disease, the significant enlargement of tumor volume can lead to upper respiratory tract obstruction, which subsequently causes the affected animals to die of asphyxiation. This disease markedly reduces the production performance of infected animals, causing economic losses to the livestock industry. Moreover, it poses a threat to precious local breeds and core breeding flocks, resulting in the loss of high-quality breeding sheep. Consequently, it has become one of the major diseases threatening the sheep and goat industry. Currently, there are no vaccines or specific treatments for this disease. This article reviews enzootic nasal tumor virus in terms of the etiology, epidemiology, clinical symptoms, main pathological changes, diagnosis, and prevention and control, providing references and ideas for the prevention and control of this disease.
