Dengue Fever in Cancer Patients: A Case Series

Abstract Complications of dengue fever are understudied in oncology. In patients undergoing chemotherapy, the immunosuppressive effects of drugs increase susceptibility to infections, such as dengue, complicating diagnosis and treatment. Here, we report two cases highlighting the challenges and importance of early detection in managing dengue fever alongside chemotherapy-induced immunosuppression. Both patients presented with severe leucopenia and thrombocytopenia, common to both chemotherapy side effects and dengue, complicating clinical management. Early recognition of dengue has allowed for appropriate management, resulting in full recovery.
