Capacity restrictions at highly trafficked indoor businesses could have an outsized effect on slowing the spread of COVID-19, as well as reducing the economic and racial disparities of the pandemic, according to a new study.

Certain “super-spreader” locations, such as restaurants, gyms and grocery stores, made up just 10% of all “points of interest” but accounted for 85% of infections modeled in the study published Tuesday in the Nature peer-reviewed journal and included researchers from Stanford as well as the Chan-Zuckerberg Biohub.
