But the researchers were analyzing viral sequences to address different questions — such as the viral mutation rate — or only looked at samples isolated in the early days of the outbreak. (sciencemag.org)
Unlike the previous studies that focused on certain species or a particular RNA virus, Skalka went broad: She and her colleagues surveyed every vertebrate genome available, 48 in all, and looked for hints of 5666 RNA viral sequences from 38 known families and nine genera that were unclassified.

Viral discovery is performed on human, animals, biologics, and environmental samples using viral particle enrichment, random nucleic acid amplification, and deep sequencing followed by bioinformatics analysis for the presence of viral sequences. (bsrisf.org)
