Rare Mixed Infections; Mucormycosis with Concomitant Actinomycosis in the Post-Covid Period: A Case Series

Introduction: COVID-19 is a viral infection caused by SARSCoV2. This pandemic can have pulmonary and extrapulmonary symptoms. The immunosuppression caused by co-morbidities of patients or COVID-19 may lead to secondary microbial infections which can be bacterial, fungal, or viral. Sometimes, the co-existence of multiple infections may worsen the scenario. Case Presentation: Here, we present two known cases of diabetes mellitus of Indian ethnicity having chief complaints of mobility of upper teeth and exposed alveolar bone in the post-COVID period. Both patients were diagnosed with co-existence of two opportunistic infections; Covid-associated mucormycosis and actinomycosis (CAMA). Management: Patients were treated with surgical debridement, and antimicrobial medication and were recovered. Conclusion: We conclude that occurrence of COVID-19 infection, mucormycosis, and actinomycosis are interrelated and early diagnosis of multiple opportunistic infections is most important for better prognosis of patients. We also suggest strict monitoring of patients with co-morbidities in the post-COVID period.
