Lumpy skin disease (LSD) is a recent emerging bovine viral disease in Asia and can cause acute or subacute disease in cattle and water buffalo. The morphological feature of LSD-infected individuals is characterized by firm, slightly raised, circumscribed skin nodules of 2 to 7 cm in diameter on body parts such as the neck, legs, tail and back. The clinical symptom includes fever, inappetence, a reduction in milk production, nasal discharge, enlarged lymph nodes, and loss of body weight. LSD is transmitted primarily by arthropod vectors such as blood-feeding insects and ticks. In wildlife, the disease was reported in an Arabian oryx and seropositive wildlife for the LSDV includes African buffaloes, blue wildebeest, eland, giraffe, impala and greater kudu. However, the role of wildlife in the epidemiology of LSD is not yet well understood, perhaps because of the difficulty in monitoring the skin lesions. Since the first report of LSD in Bangladesh and China in July 2019. LSD seems to have spread over almost all divisions in Bangladesh by December 2019. In August 2019, the disease appeared in India and has spread to the southern part of India since January 2020. In June 2020 LSD appeared for the first time in the eastern part of Nepal. LSD recently continues to spread in the East and South Asian regions, including various provinces spanning South and East China, as well as Nepal, India and Bhutan. The recent rapid spread of disease in Asian countries indicates the importance of understanding the distribution routes and transmission vectors of LSD. The presentation is designed to provide existing information on the various aspects of the disease, focusing on current distribution, transmission vectors and the potential role of wildlife in the further spread of LSD.
