Dengue virus infection in hematopoietic stem cell transplant recipients: A case series and comparative literature review from dengue endemic region.

This case series describes the wide spectrum of clinical presentation, laboratory findings, and morbidity/mortality associated with dengue fever in hematopoietic stem cell transplant recipients, treated in a dengue endemic region. The risk of acquiring viral infections increases manifold after transplant due to the severely immunocompromised state amid conditioning toxicity and immunosuppressive therapy. The classical warning signs of dengue viremia are often masked in posttransplant patients, leading to a missed diagnosis of dengue and grave consequences observed in some of the patients.
