An overview of opportunistic fungal infections associated with COVID-19

Abstract

The COVID-19 survivors and long-term steroid administered patients exhibit a variety of fungal co-infections. The lives of COVID-19 patients and survivors are hampered by fungal species of the genera Candida, Aspergillus, and Mucor. There have been cases of mucormycosis, aspergillosis, and candidiasis in COVID-19 patients. The treatments given to these opportunistic fungal infections include polyene like amphotericin B, azoles including imidazoles like ketoconazole, miconazole, and triazoles like fluconazole, voriconazole, itraconazole, Echinocandin derivatives like- caspofungin, micafungin, immunomodulatory therapy, granulocyte transfusion, etc. A successful recovery and the reduction of fatalities depend on prompt diagnosis and treatment. To reduce mortality, advanced techniques to identify such uncommon infections at a very early stage are necessary. This review's goal is to provide a summary of the systemic and superficial opportunistic fungal infections that the COVID-19 survivors were dealing with, including information on illness incidence, pathogenicity, and treatment.
