nvestigation of SARS-CoV-2 Genomic Changes in Comparison with COVID-19 Sequence in Iran

The corona virus (COVID-19) is a positive, single-stranded RNA virus. The virus mutates both naturally and after transmission to humans, transmitting it from patients to others, causing an increase in the mutation in its genome. Mutations in the virus have helped it adapt to different conditions and increase the pathogenicity of new individuals. Examination of mutated sites can be helpful in diagnosis and treatment. Differences in virus nucleotides vary not only in different hosts but also in sequences prepared from human samples in different countries, which raises the important question of which virus each country seeks to treat, diagnose, and develop its own vaccine. , Get more strength.
