Dengue and malaria infections are common mosquito-borne infectious diseases in tropical and subtropical regions. The clinical manifestations of dengue and malaria often mimic each other, causing the predicament of early diagnosis without laboratory investigations. Concurrent dengue and malaria infection are often rare scenarios when both diseases occur in a particular patient at the same time. A high index of suspicion is therefore required to establish an early diagnosis to ensure complete success in its management. This case report is about concurrent dengue and malaria infection in a 54-year-old Pakistani man who presented with high-grade fever for three days before admission. On examination, he was febrile (38.8°C) with no other findings. His blood investigations were positive for NS1 antigen and IgM but negative for IgG. His peripheral blood film revealed the presence of Plasmodium vivax. He was treated for dengue fever with supportive management and started with oral Riamet (artemether and lumefantrine) along with oral primaquine 30 mg daily for two weeks’ duration. Following treatment, the patient demonstrated progressive clinical improvement and was subsequently discharged back to the community clinic for the continuation of care.
