Case Report: False-Positive Dengue Non-Structural Protein 1 Antigen in a Patient with COVID-19 Infection
Abstract
Abstract: Early diagnosis of dengue fever and COVID-19 is made very easy due to technological advancements. The non-structural protein 1 antigen test strips are widely used in various regions; however, false-positive events have begun to be reported in the dengue-endemic areas with the COVID-19 pandemic, even though statistically non-structural protein 1 antigens are very specific to dengue infection. We reported a case of the false-positive non-structural protein 1 test in a patient with COVID-19 infection.
