TEHRAN (Iran News) – Scientists have identified an underlying genomic signature for 29 different COVID-19 DNA sequences.

This new data discovery tool will allow researchers to quickly and easily classify a deadly virus like COVID-19 in just minutes—a process and pace of high importance for strategic planning and mobilizing medical needs during a pandemic, Phys reported.

The study also supports the scientific hypothesis that COVID-19 (SARS-CoV-2) has its origin in bats as Sarbecovirus, a subgroup of Betacoronavirus.

The findings, Machine learning using intrinsic genomic signatures for rapid classification of novel pathogens: COVID-19 case study, were published in PLOS ONE.

The “ultra-fast, scalable, and highly accurate” classification system uses a new graphics-based, specialized software and decision-tree approach to illustrate the classification and arrive at the best choice out of all possible outcomes. The entire method uses a new graphics-based, specialized software to illustrate the best choice out of all tested possible outcomes.

Biology professor Kathleen Hill co-led the study with Western collaborators in Computer Science and Statistical and Actuarial Sciences, along with others at the University of Waterloo’s Department of Computer Science.

The machine-learning method achieves 100 percent accurate classification of the COVID-19 sequences and more importantly, discovers the most relevant relationships among more than 5,000 viral genomes again within minutes.

“All we needed was the COVID-19 DNA sequence to discover its own intrinsic sequence pattern. We used that signature pattern and a logical approach to match that pattern as close as possible to other viruses and achieved a fine level of classification in minutes—not days, not hours but minutes,” Hill said.

This classification tool has already been used to analyze more than 5,000 unique viral genomic sequences, including the 29 COVID-19 sequences available on Jan. 27.

Hill believes the tool, which is able to classify any newly discovered virus sequence COVID-19 or otherwise, will be an essential component in the toolkit for vaccine and drug developers, front-line health-care workers, researchers, and scientists during this global pandemic and beyond.
