Like other living organisms, viral genomes are made of DNA or RNA. Viral sequencing involves determining the sequence of the viral genome, which provides information about the virus's basic genetic makeup.
Furthermore, viral sequencing can reveal mutations in the viral genome and help identify new strains of the virus. While not all viruses are deadly, their variants can be, so sequencing is crucial for identifying different strains. Methods for sequencing viral genomes, including whole genome sequencing, metagenomic, and PCR amplicon sequencing, provide accurate information about virus sequences, revolutionizing virus identification
