Dengue fever is a viral infection that is transmitted from mosquitoes to humans. It is more prevalent in tropical and subtropical environments. A total of 389 individuals, who presented with febrile illness at the NIBD clinics, were screened for dengue and malaria with Complete Blood Count (CBC), Dengue nonstructural protein 1 (NS1) antigen test and Malaria Parasite Immunochromatographic test (MP-ICT).
