Objective: To summarize the clinical characteristics and diagnosis and treatment process of a child with chronic active EB virus infection associated hemophagocytic syndrome, and improve the understanding of this disease. Methods: Retrospective analysis of the clinical characteristics and diagnosis and treatment process of a child with chronic active EB virus infection associated hemophagocytic syndrome admitted to the pediatrics department of Weihai Municipal Hospital affiliated with Shandong University in October 2022, and relevant literature review. Results: The child presented with prominent symptoms such as fever, repeated liver damage, decreased whole blood cells, and coagulation dysfunction. The condition developed rapidly and died within a short period of time. Combined with relevant examinations, the diagnosis was chronic active EB virus infection associated hemophagocytic syndrome. Conclusions: For children with chronic active EB virus infection, effective treatment measures should be actively taken after a clear diagnosis. Once it causes related hemophagocytic syndrome, the mortality rate is extremely high.
