Abstract

Prevalence of malaria and dengue infection coexistence is increasing during endemic periods although causing quite similar symptoms and signs, the treatment of these two illnesses is different. Any suspicion of malaria in disease-endemic areas must be excluded with microscopy and/or rapid antigen test. Objective: To find out the incidence of co-infection of dengue and malaria based on clinical and hematological parameters in patients presenting with acute febrile illness. Methods: This cross-sectional study was done in the Medicine Unit of Jinnah hospital, Lahore from October - December 2022. 140 diagnosed as dengue fever by Non-Structural Protein 1 (NS1) and IgM were included in the study. All the cases were subject to a thorough medical examination i.e. complete battery summary of temperature together with the serology of Dengue, X-ray of the chest, abdominal ultrasound scan, renal function test (RFT), liver function test (LFT), malarial parasite slide, complete blood count with peripheral smear etc. Accordingly, the treatment was given to them with follow-up medical evaluation including detailed investigations.  Data were entered and analyzed in SPSS version. 27.0 and presented as frequency and percentages. Chi square test was used to assess statistical significance with P < .05.  Results: Mean age of respondent was 35.5 + 15.6 years. Co-infection rate with malaria and severe disease along with prolong duration fever and persistent thrombocytopenia among subjects was15.0%. Conclusions: Majority of co infected individuals were having severe disease, with subsequent development of disseminated intravascular coagulation and sepsis, responding well to anti-malarial treatments
