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). Whole blood samples were collected and analyzed for CBC on Sysmex XN hematology analyzers. All 65 CPD and standard CBC parameters were analyzed. Statistical analysis was performed using SPSS version 25.0. Descriptive analysis of all the parameters was performed and a p value < 0.001 was considered significant. Positive and negative correlation was also evaluated within the parameters to assess their significance.
