Covid-19 New Variant: Tracking the host variability of the virus in individuals and populations over time can provide important clues to sites that are likely to benefit and harm, scientists say


New Delhi. Scientists from different research institutes have claimed to have discovered the mystery of the origin of the new type of coronavirus. In research published on July 27 on the preprint server MedRxiv, scientists have said that the virus undergoes changes in the body of an infected person and once it does, it infects new people with the same changes. This results in the emergence of new variants. The team found that after sequencing about 80 percent of the genome in individuals, a new variant or strain emerged.


Scientists say that tracking the host variability of the virus in individuals and populations over time can provide important clues to sites that are likely to benefit and harm. According to the study, this information will be very useful for predicting the spread and infectivity of the type of virus spread in the population. Analysis of novel coronavirus genomes combined with intra-host variability should now be the next step.

These institutes involved in the research, including

the Center for Cellular and Molecular Biology (CCMB), Hyderabad, Institute of Genomics and Integrative Biology (CSIR-IGIB), Delhi, Institute of Life Sciences, Bhubaneswar, Academy for Scientific and Innovative Research, Researchers from Ghaziabad, National Center for Disease Control, New Delhi and Indian Institute of Technology, Jodhpur participated in the study.

The researchers analyzed samples from Kovid-19 patients from two different periods of the pandemic. In the first phase, the team analyzed 1,347 samples collected up to June 2020 from different populations in China, Germany, Malaysia, the United Kingdom, the United States, and India, to determine the genome-wide intra-host single locus in COVID-19 patients. Nucleotide variation (iSNV) map to be experienced. Single Nucleotide Variation (SNV) is the substitution of one nucleotide (nucleic acid or a basic building block of genetic material) for another.
