Lumpy skin disease (LSD) is a serious emerging infectious disease in cattle caused by a virus of the family Poxviridae. According to the Department of Animal Health, LSD first occurred in Vietnam at the end of October 2020 in Cao Bang and Lang Son provinces. So far, the disease has infected over 63,000 animals, resulting in 9170 deaths occurring in 32 different provinces in northern and central Vietnam. In this study, skin samples from lumpy skin disease virus (LSDV)-infected cattle from the northern provinces of Vietnam displaying clinical symptoms including fever (> 40 °C), runny nose, drooling, and skin lesions were used for genetic characterization and histopathology. Genetic analysis of the partial P32 (LSDV074), partial F (LSDV117), complete RPO30 (LSDV035), and complete G-protein-coupled-chemokine-like receptor (GPCR) (LSDV011) genes showed that all Vietnamese LSDV strains belonged to the genus Capripoxvirus and were closely related to LSDV strains isolated in China. Microscopic examination of the skin lesions showed thickening of the epidermal layer of the skin and hair follicles, hyperplasia of sebaceous glands, intracytoplasmic inclusion bodies, and hemorrhages in the mesoderm.
