Collateral Presentation of Malaria and Dengue Viral Hemorrhagic Fever: A Rare Case.

Cases on concurrent infection of dengue and malaria are uncommon in Pakistan. Dengue and malaria are the two very common, mosquito-borne infections, which may have significant morbidity and mortality if not managed properly. Concurrent infections of dengue and malaria are rare due to the different habitats of its vectors and activities of different bearer mosquitoes. The first case was reported in 2005. Since then, several co-existing infections have been reported consisting of the dengue virus (DENV) and the malaria protozoans. Symptoms of each infection may be disguised by a coincident second infection, resulting in delayed treatment and severe complications. We report a case of concurrent malaria and dengue viral hemorrhagic fever in a 19-year-old male.
