Lumpy Skin Disease (LSD) is a major transboundary viral disease affecting cattle, characterized by cutaneous nodules, fever, and systemic manifestations. In Algeria, its recent emergence poses significant threats to livestock health and the agricultural economy. This study aimed to analyze the spatiotemporal distribution of LSD outbreaks and assess associated biochemical alterations in infected cattle. Epidemiological data were collected from veterinary surveillance reports and analyzed using Geographic Information Systems (GIS). The results revealed a wide geographic spread of LSD, with a higher concentration of outbreaks in northern regions during the summer, highlighting the role of climatic conditions and vector activity in disease transmission. Biochemical analysis showed significant differences between infected and healthy cattle. Infected animals exhibited lower glucose levels and significant increases in urea and creatinine, along with decreased total proteins, albumin, and globulins. Liver enzymes (AST and ALT) were significantly elevated, while calcium levels were markedly reduced (p < 0.05). These findings indicate that LSD is a systemic disease associated with metabolic and organ dysfunctions. Integrating biochemical parameters with epidemiological surveillance could improve disease monitoring and control strategies.
