Even before the vast majority of states were loosening the measures intended to keep people physically distant and slow the spread of the coronavirus, people were starting to travel further and see each other more, according to research from Northeastern’s Network Science Institute.

SARS-CoV-2, the coronavirus that causes COVID-19, was circulating in major U.S. cities as early as January, says Alessandro Vespignani, director of Northeastern’s Network Science Institute. And if we want to keep our communities safe going forward, we need to understand how we missed a virus that was right under our noses.

Herd immunity is the idea that a disease can’t spread through a population once a large enough percentage is immune, either because they’ve recovered from an infection or received a vaccine. But that won’t work with SARS-CoV-2, the coronavirus that causes COVID-19, said Samuel Scarpino, an assistant professor who runs the Emergent Epidemics lab at Northeastern

Researchers at Northeastern mapped the way proteins within human cells behave after the cells are hijacked by the virus to identify drugs that might be able to fight it. The team is now working with other experimental researchers to begin testing those drugs.

After days of closures and requests—or orders—to stay home, many people caught in the heart of the COVID-19 pandemic are wondering if these efforts will be enough. Network scientist Alessandro Vespignani says the answer depends on the ways that local, regional, and federal governments use the time.

“Either the screening, detection, and isolation in China will be able to contain the epidemic there, or it will be a global issue,” says Alessandro Vespignani, Sternberg Family Distinguished University Professor at Northeastern. “And this will be decided in the next couple of weeks.”

Environmental factors drive the majority of our risk for non-communicable diseases, says Albert-László Barabási, Robert Gray Dodge Professor of Network Science at Northeastern. We need to be studying them.
