COVID-19 Pneumonia and Dengue Fever Coinfection in an Individual From Southeast Asia

Abstract
COVID-19 infection is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which was declared a pandemic in 2020. Dengue fever (DF) is caused by the dengue virus (DENV) from the Flaviviridae family and is transmitted via the bite of the female Aedes aegypti mosquito. COVID-19 pneumonia and dengue fever coinfection is a relatively difficult diagnosis to be established considering the similarities in the clinical manifestation of both diseases. I hereby report an unusual case of dual diagnosis involving COVID-19 pneumonia and dengue fever (DF) on the same day of presentation to the hospital. A 62-year-old male presented to the emergency department with a fever of six days duration associated with chills, rigors, arthralgia, myalgia, and a generalized pinpoint rash over the chest and abdomen. He had contact with a worker who recently tested positive for COVID-19. However, his vital signs were stable with peripheral capillary oxygen saturation (SPO2) of 99% under room air. Laboratory investigations showed polycythemia, increased hematocrit levels, and thrombocytopenia. Liver function tests showed evidence of acute hepatitis. Otherwise, the basic metabolic panel and coagulation profile were normal. Viral screens for hepatitis B, hepatitis C, and human immunodeficiency virus (HIV) were negative. The posterior-anterior chest radiograph of the patient showed ground glass opacity in both middle and lower zones of the lungs, which is mostly peripheral with preservation of lung markings. The diagnosis was confirmed by a positive SARS-CoV-2 polymerase chain reaction (PCR) test with a cycle threshold (CT) value of 19.97 and positive immunoglobulin M (IgM) and immunoglobulin G (IgG) titers on the dengue serology panel on the same day of testing. Predisposing risk factors were chronic medical illnesses (type 2 diabetes mellitus, hypertension, and ischemic heart disease) and exposure to probable COVID-19-infected individuals. The patient fully recovered after treatment with oral paracetamol 1 g four times a day for five days and an intravenous drip of 0.9% sodium chloride for 24 hours.
