The coronavirus disease 2019 (COVID-19) pandemic emerged in Wuhan, China, in late 2109, and has rapidly spread around the world. Until May 25, 2020, there were 133,521 confirmed COVID-19 cases and 7359 deaths in Iran. The role of opportunistic fungal infections in the morbidity and mortality of COVID-19 patients remains less defined. Based on our multicenter experiences, we categorized the risks of opportunistic fungal infections in COVID-19 patients in Iran. The COVID-19 patients at high risk included those with acute respiratory distress syndrome, in intensive care units, receiving broad-spectrum antibiotics, immunosuppressants or corticosteroid, and supported by invasive or noninvasive ventilation. The patients were most likely to develop pulmonary aspergillosis, oral candidiasis, or pneumocystis pneumonia. Most diagnoses were probable as the accurate diagnosis of opportunistic fungal infections remains challenging in resource-poor settings. We summarize the clinical signs and laboratory tests needed to confirm candidiasis, aspergillosis, or pneumocystosis in our COVID-19 patients.
