Nature – “How to stop restaurants from driving COVID infections – US mobile data suggests restaurants, gyms and cafes can be covid hotspots — and reveals strategies for limiting spread. In cities worldwide, coronavirus outbreaks have been linked to restaurants, cafes and gyms. Now, a new model using mobile-phone data to map people’s movements suggests that these venues could account for most COVID-19 infections in US cities. The model, published in Nature today, also reveals how reducing occupancy in venues can significantly cut the number of infections. The model “has concrete pointers as to what may be cost-effective measures to contain the spread of the disease, while at the same time, limiting the damage to the economy”, says Thiemo Fetzer, an economist at the University of Warwick in Coventry. “This is the policy sweet spot.”
