Hamilton scientists Zobia Jawed and Gail Krantzberg say that the new COVID-19-tracking project they’re running at McMaster University relies on a “bottom-up” approach. That’s in reference to the fact that the effort relies on forming partnerships across the province, but it can also be taken another way: the professors want to develop an Ontario-wide method for detecting the novel coronavirus in municipal sewage systems. “This is just an amazing project to look at, because it’s different,” Jawed says. “It’s unique.”
