Coronavirus disease 2019 (COVID-19) is the seventh member of the bat severe acute respiratory syndrome (SARS) family. COVID-19 can fuse their envelopes with the host cell membranes and deliver their genetic material. COVID-19 attacks the respiratory system and stimulates the host inflammatory responses, enhances the recruitment of immune cells, and promotes angiotensin-converting enzyme 2 (ACE2) activities. Patients with confirmed COVID-19 may have experienced fever, dry cough, headache, dyspnea, acute kidney injury (AKI), acute respiratory distress syndrome (ARDS), and acute heart injury. Several strategies such as oxygen therapy, ventilation, antibiotic or antiviral therapy, and renal replacement therapy are commonly used to decrease COVID-19-associated mortality. However, these approaches may not be good treatment options. Therefore, the search for an alternative-novel therapy is urgently important to prevent the disease progression. Recently, microRNAs (miRNAs) have emerged as a promising strategy for COVID-19. The design of oligonucleotide against the genetic material of COVID-19 might suppress virus RNA translation. Several previous studies have shown that host miRNAs play an anti-viral role and improve the treatment of patients with COVID-19. miRNAs by binding to the 3'-UTR or 5'-UTR of viral RNA play an important role in COVID-19-host interplay and viral replication. miRNAs interact with multiple pathways and reduce inflammatory biomarkers, thrombi formation, and tissue damage to accelerate the patient outcome. The information in this review provides a summary of the current clinical application of miRNAs for the treatments of patients with COVID-19. This article is protected by copyright.
