Dengue fever is a mosquito-borne infection that co-circulates with Chikungunya and Zika virus infection in many parts of the world. Dengue virus (DENV) is occasionally responsible for acute hepatitis and a few cases of acute hepatitis due to co-infection with DENV and hepatitis E virus have been described in India. A 37-year-old Cuban woman living in Italy was admitted to our hospital with a presumed arboviral infection upon her return to Italy short after a 15-day trip to her home-country to visit relatives. An acute infection due to DENV serotype 1 was initially diagnosed, following a clinical course characterized by signs of liver dysfunction that were possibly due to co-infection with hepatitis E virus.
