Case in brief

A stem cell transplant recipient developed severe dengue following a blood transfusion during the 2024 dengue epidemic in Brazil. Phylogenetic analysis confirmed the transmission of the virus through the transfusion, leading to a fatal outcome. This case underscores the heightened risk of severe dengue in immunocompromised patients receiving transfusions.

Diagnostic / clinical pearl

Clinicians should be aware of the risk of transfusion-transmitted dengue, especially in immunocompromised patients, during dengue outbreaks.

Why it matters

This case emphasizes the need for vigilance in blood safety protocols during dengue epidemics to protect vulnerable populations.
