This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Initial epidemiological studies inform the central COVID-19 disease prophet. Some papers have been studying miRNA and viral RNA interaction target predictions over the past few years. In this work, via the miRDB database, we determined the target scores of predicted miRNA to bind with the ss-RNA of SARS-CoV-2 in general and spike gene in specific. Our predicted miRNA targets of the ss-RNA of SARS-CoV-2 might destabilize and hence inhibit the ss-RNA translation of SARS-CoV-2 and prevent viral replication that has been established by more than 80% of asymptomatic infected cases in Jordan due to host miRNA interactions. In respiratory epithelial cells, the high scoring miRNAs prediction covers the RNA from 5' to 3' that explain successful antiviral defenses against ss-RNA of SARS-CoV-2 and lead to new nucleotide deletion mechanisms. The exciting finding here that the substitution 1841A>G at the viral genomic RNA level or the D614G at spike protein level showed a change in the predicted miRNA sequence and an increase in the target score (from 91 to 92) (hsa-miR-4793-5p to hsa-miR-3620-3p).
