Introduction: Diabetes mellitus (DM) and steroid medication, coincided with coronavirus disease 2019 (COVID-19), results in a weakened immune system, allowing some commonly found pathogens to become more harmful. Mucormycosis (black fungus) is such a type of opportunistic infection caused by fungi belonging to the Mucorales family. DM is the most prominent risk factor for mucormycosis. Excessive blood sugar and decreased insulin levels lead to diabetic ketoacidosis (DKA), a devastating complication of DM that can be fatal if left untreated. Methods: Diabetic ketoacidosis is more common in type 1 diabetic patients, although it can also be fall in type 2 diabetic patients. DKA occurs when the body lacks enough insulin to allow blood sugar to enter the cells and is used for energy. Instead, the liver breaks down fat for fuel producing chemicals known as ketones in the process. Results: When too many ketones are created too quickly, they can reach dangerously high levels in the body. Mucormycosis is a rare but serious infectious disease that requires medication or surgical removal. Conclusion: The confluence of diabetes and COVID-19 makes managing mucormycosis a serious and dead issue. Although the effectiveness of prophylactic antifungal therapy has yet to be demonstrated, hyperglycemia control appears to be the most important step in managing mucormycosis in DKA patients.

Background: Coronavirus disease 2019 (Covid-19) is caused by a novel coronavirus (SARS-CoV-2) infection, while influenza viruses cause the flu. SARS-CoV-2 and influenza virus co-infection seems to be a real and serious concern. Objective: This study aimed at evaluating the clinical features, laboratory investigations, computed tomography scans, and interventions of Covid-19 patients during seasonal influenza. Methods: This was a multi-center prospective cohort study that collected data from hospitals, clinics, and laboratories on measurements, treatments, and outcomes from Covid-19 patients admitted to temporary Covid-19 care centers. Results: A total of 480 individuals (female, 231 [48.12%]; male, 249 [51.88%]) were recruited from March 31st to May 14th, 2021 at five hospitals/clinics in Uttar Pradesh, North India. The patients were divided into six groups based on their age (65+ years [25.41% of cases] being the most affected age) and five groups based on their conditions (asymptomatic 65 [13.54%], mild 94 [19.58%], moderate 206 [42.91%], severe 84 [17.50%] and critical 31 [6.45%]). Patients’ outcomes were documented as death (19 [3.95%]), recovery (421 [87.71%]) and under-treatment (40 [8.34%]). Conclusions: The most common clinical symptoms reported were fever, sore throat, and dyspnea. The severity was linked to the presence of hypoxemia, lymphocytopenia, thrombocytopenia, elevated erythrocyte sedimentation rate (ESR), and high blood urea nitrogen (BUN). The vast majority of patients were given symptomatic treatment. To distinguish between Covid-19 and the seasonal flu, any onset of fever should be suspected and examined for the viral strain.
