While the world continues to battle with the pandemic of Coronavirus disease 2019 (COVID-19), the issue of post COVID-19 complications has emerged as a significant problem. Post COVID-19 complications may be associated with a wide range of bacterial and fungal co-infections. The main reason behind the co-infections is the use of corticosteroids and other adjunctive therapies to arrest any possibility of cytokine storm syndrome that may occur in critically ill patients. One such deadly post COVID-19 complication on rise is mucormycosis. It is an aggressive opportunistic fungal infection known to be associated with poor prognosis if not diagnosed and treated on-time. Classically, uncontrolled diabetes mellitus (DM) and other immunosuppressive conditions including corticosteroid therapy are known risk factors for mucormycosis.
