The authors have also highlighted the role of factors like newer variants, the role of cytokine storm, industrial oxygen and unhygienic ventilation systems in the pathogenesis of CAM. While we agree with them, it would be worthwhile to remember that the evidence regarding the different facets of this disease is gradually accruing with time. For example, a recent large-scale study by the COSMIC group included 2826 patients with CAM, out of which 43% of the patients did not require oxygen therapy. 2 Immunosuppression is a well-known risk factor for mucormycosis and a large proportion of their patients (87%) had received steroids. Interestingly, the dose of steroids was higher in those with severe disease that may act as a confounding factor in ascertaining the role of severity of disease in CAM. The study by MucoCovi network also reported that only 40% of the CAM patients had hypoxemia; however, the details of …
