A 36-years-old man from West Africa was admitted to our ED with respiratory failure and a 15 days history of fatigue and peevish cough. He reported watery diarrhea and a 30 kg weight loss in the last three months. In his clinical history, he did not make any recent trips abroad, nor did he reported any chronic disease, any contact with domestic or wild animals or any drug abuse. He received a complete vaccination course for SARS-CoV-2. On the physical examination we observed low-grade fever, bilateral diffused crackles on chest auscultation, latero-cervical and supra-clavicular lymphadenopathies and a maculopapular rash spread on the upper limbs and trunk.
