Coronavirus Disease 2019 (COVID-19) severity and Diabetes mellitus affect each other bidirectionally. The plus-sense single-stranded RNA (+ssRNA) genome of the SARS-CoV-2 virus can be targeted and suppressed by the host cell’s microRNAs (miRNAs). Using the differential gene expression analysis between the mock-infected and the SARS-CoV-2-infected pancreatic tissue, we report five Diabetes-associated genes that are upregulated due to SARS-CoV-2 infection in the hESC pancreas tissues. Ten miRNAs regulating these five genes can potentially target the SARS-CoV-2 genome. We hypothesize that the SARS-CoV-2 genome copies in the infected human pancreas cell compete with the host cell’s native genes in being regulated by the native miRNAs. It leads to the reduced miRNA-regulation and, thus, the upregulation of the Diabetes-associated native genes. Thus, the resultant new-onset or elevated Diabetic symptoms may worsen the condition of COVID-19 patients.
