[Dengue and SARS-CoV-2 coinfection in an HIV positive patient].

Dengue is a mosquito-borne viral disease confined to the geographical areas where its vectors Aedes aegypti and Aedes albopictus are present. The transmission occurs mainly during the summer but it can extend to autumn months in warm climates. In our country, this year the seasonal transmission o f dengue overlapped with the COVID-19 pandemic, caused by SARS-CoV-2, a novel coronavirus responsible of serious respiratory conditions with eventual fatal outcomes. On the other hand, the HIV is a retrovirus that causes disease by weakening the immune system, favoring infections by numerous opportunistic pathogens. We present the case of an untreated HIV patient who developed simultaneous infection with dengue and SARS-CoV-2 with favorable evolution.
