Abstract
BACKGROUND

Coronavirus disease 2019 (COVID-19) patients who suffer severe infection or comorbidities have an increased risk of developing fungal infections. There is a possibility that such infections are missed or misdiagnosed, in which case patients may suffer higher morbidity and mortality. COVID-19 infection, aggressive management strategies and comorbidities like diabetes render patients prone to opportunistic fungal infections. Mucormycosis is one of the opportunistic fungal infections that may affect treated COVID patients.

CASE SUMMARY

We present a case series of four adult males who were diagnosed with mucormycosis post-COVID-19 recovery. All the patients had diabetes and a history of systemic corticosteroids for treatment of COVID-19. The mean duration between diagnosis of COVID-19 and development of symptoms of mucor was 15.5 ± 14.5 (7–30) d. All patients underwent debridement and were started on antifungal therapy. One patient was referred to a higher center for further management, but the others responded well to treatment and showed signs of improvement at the last follow-up.

CONCLUSION

Early diagnosis and management of mucormycosis with appropriate and aggressive antifungals and surgical debridement can improve survival.

Core Tip: Mucormycosis usually indicates a serious underlying medical condition such as diabetes. Furthermore, the immune dysregulation post coronavirus disease 2019, and widespread use of immunosuppressants and broad-spectrum antibiotics may lead to enhanced susceptibility to a number of secondary opportunistic infections such as mucormycosis. Clinical suspicion along with prompt microbiological diagnosis are indispensable to a positive case outcome.
