A Doença da Dermatose Nodular Contagiosa (Lumpy Skin Disease – LSD) é uma importante doença viral transfronteiriça que afeta bovinos, caracterizada por nódulos cutâneos, febre e manifestações sistêmicas. Na Argélia, seu surgimento recente representa uma ameaça significativa à saúde do rebanho e à economia agrícola. Este estudo teve como objetivo analisar a distribuição espaço-temporal dos surtos de LSD e avaliar as alterações bioquímicas associadas em bovinos infectados. Os dados epidemiológicos foram coletados a partir de relatórios de vigilância veterinária e analisados utilizando Sistemas de Informação Geográfica (SIG). Os resultados revelaram uma ampla distribuição geográfica da doença, com maior concentração de surtos nas regiões do norte durante o verão, destacando o papel das condições climáticas e da atividade dos vetores na transmissão da doença. A análise bioquímica mostrou diferenças significativas entre bovinos infectados e saudáveis. Os animais infectados apresentaram níveis mais baixos de glicose e aumentos significativos de ureia e creatinina, além de redução das proteínas totais, albumina e globulinas. As enzimas hepáticas (AST e ALT) estavam significativamente elevadas, enquanto os níveis de cálcio estavam marcadamente reduzidos (p < 0,05). Esses achados indicam que a LSD é uma doença sistêmica associada a disfunções metabólicas e orgânicas. A integração de parâmetros bioquímicos com a vigilância epidemiológica pode melhorar o monitoramento e as estratégias de controle da doença.
