Background: Till the moment of editing this paperwork, WHO announced that there is no specific drugs or vaccines for treatment or prophylaxis of COVID-19. Additionally during the global gradual unlocking of community restrictions, WHO warned form another wave of the disease during the next few months. So clinicians and radiologists during this second wave would face great challenges in differentiation between COVID-19 and other virulent influenza viruses, mainly H1N1. Objective: to establish comparative radiological study between COVID19 and H1N1 to find differentiating criteria that would help during their expected clinico-laboratory and radiological overlap in next Influenza season. Material and methods: Retrospective study was including 130 patients; 65 COVID-19 patients and 65 H1N1 patients. HRCT findings to be analyzed by three expert consultant radiologists.
