Bengaluru: The SARS-CoV-2 virus, which causes COVID-19, is mutating faster in Bengaluru, compared to the national and global average mutation rate according to a study conducted by a group of researchers from the Indian Institute of Science (IISc). The virus samples from Bengaluru had 27 mutations in their genomes, with over 11 mutations per sample. This is higher than both the national average of 8.4 and global average of 7.3.
The study also found that samples of the virus in India have not evolved from a single ancestral variant but have multiple origins.
The study involved a process called next generation sequencing (NGS) which allows rapid sequencing of the entire genome. In a statement from IISc, Professor Utpal Tatu, who led the research team, was quoted as saying that sequencing the genomes of viral strains from around the world is important to keep track of mutations that are constantly arising. While the SARS-CoV-2 genome codes for more than 25 proteins, a han
