Abstract Background Impaired hemostasis, especially coagulopathy contribute to bleeding manifestations in dengue fever. Parameters such as partial thromboplastin time (PTT) and prothrombin time (PT) indicate the impact of dengue on coagulation system. Objective To identify the impact of dengue infection on the PT and PTT coagulation tests Method A prospective study was conducted which included 334 cases of dengue caused by dengue virus along with 101 cases of control. Patients who were reported for clinically dengue infection were enrolled. Laboratory-positive dengue cases were confirmed by immune chromatography and WHO criteria were used for classifying the dengue severity. Plasma PT and PTT were performed. Results There was a highly significan
