Viral sequencing being done at UW-Madison catches mutations, guides effective public health response

As COVID-19’s effects have mounted to a dizzying scale, a team of UW–Madison scientists has kept its focus on the tiniest shifts in the virus’s genetic material. Beginning with the first known case of the virus in Wisconsin a year ago, CMB trainers David O’Connor and Thomas Friedrich have been sequencing the genomes of as many virus samples as they can process — adding to a family tree of infections globally to help fight the disease on intercontinental, interpersonal and intercellular scales. A bill introduced in Congress last week by Wisconsin Sen. Tammy Baldwin seeks to build on their success.
