Core Tip
Core Tip: Co-incidence of coronavirus disease 2019 (COVID-19) and influenza in the influenza season can be challenging for the health system. The management, prognosis, and protection for these two viral pneumonias differ considerably. Chest computed tomography (CT) has a high sensitivity for detection of pulmonary disease manifestations and can be helpful in diagnosing COVID-19. In this review, we made a comparative study of CT findings in COVID-19 and influenza A pneumonia, as well as their clinical manifestations, by a thorough review of literature. Delineation of differences observed in the chest CT scan of COVID-19 and influenza can be helpful in differentiation.
