A biochemistry laboratory at SIU School of Medicine is sequencing the genomes of SARS-CoV-2 viruses that cause COVID-19 to determine if distinct variants exist in different Illinois communities and specifically in rural versus metropolitan areas. “We’re looking for the ‘personality’ of the genome, to see how it’s changing over time,” says Keith Gagnon, PhD, assistant professor in the Department of Biochemistry and Molecular Biology. “There are a couple of variants and we need to determine which is the most dangerous. Based on what we learn, we can tell the virus’ point of origin, whether it’s
