A case series of atypical manifestations of dengue

Abstract

Dengue fever is an arthropod-borne viral illness caused by Flavivirus and transmitted by Aedes aegypti mosquito. With rising burden of disease, atypical manifestations have increased. In our case series, we report five cases of serologically proven dengue-positive patients (by immunochromatographic dengue card test) with atypical manifestations. The first two patients presented with dengue encephalitis and the next two patients presented with viral pneumonia. The second, fourth, and fifth cases were dengue in cirrhotic patients leading to decompensated liver disease. The fourth case succumbed to death due to refractory shock. We should have a high index of suspicion and knowledge to detect atypical manifestations of dengue fever as they are more fatal and are increasing in incidence. In preexisting liver disease, chances of bleeding are high even though platelet counts are not very low. Only appropriate timely intervention can prevent morbidity and mortality.
