In recent years, microRNAs (miRNAs) are potential diagnostic and therapeutic agents for viral infections. Here, we aimed to investigate the expression of microRNAs in the identification and treatment of viral infections.MiRNAs are non-coding molecules that control gene expression and participate in numerous biological processes, including host immunity and pathogen duplication. MiRNAs have played a role in the pathogenesis of various viral infections, such as HIV and HCV. Their presence in the tissues and serum of infected patients has been demonstrated to help predict disease progression, identify disease subtypes, and evaluate treatment responses.Research has shown that miRNAs can detect viral infections by identifying specific miRNAs in serum. For example, miRNA expression profiling was recently used to distinguish between hepatitis C and hepatitis B viral infections precisely. Furthermore, miRNAs can be used to detect the presence of multiple viral infections simultaneously by assessing the expression levels of these miRNAs. Also, miRNAs can differentiate between different genetic variants of the same virus, which is useful for identifying emerging viral strains or drug-resistant ones.MiRNAs have been identified as being a factor in treating viral infections. For example, miRNA mimics have decreased gene expression and halted viral replication in HIV, HCV, and EBV. Moreover, microRNA antagonists have been utilized to inhibit pro-inflammatory cytokines, thereby modulating the immune response and the severity of infections.
