The probable source of origin of Indian SARS-CoV-2 viruses is countries from Europe and Oceania regions, besides Middle East and South Asian regions, says a research article published in Current Science. Comparison of genome sequences from diverse locations allows identification of the genetic diversity among viruses, the researchers say, adding that the aim of the study was to determine the genetic diversity among Indian SARS-CoV-2 isolates. An in-depth analysis of 558 viral genomes derived from samples representing USA, Europe, China, East Asia, South Asia, Oceania, Middle East regions, and India revealed that most Indian samples are divided into two clusters,” it states. In contrast, cluster B grouped with countries from Europe, Middle East and South Asia. Expanding on the viral clade analysis of Indian samples, the study says the potential origin could be countries mainly from Europe, Middle East Oceania and South Asia regions, which strongly imply the spread of virus through most-travelled countries.
