“While many restaurants, bars and gyms shut down during the pandemic, others have continued operating with limited capacity. New research shows this sacrifice could be effective at curbing transmissions — and density caps may offer one way to keep the economy humming along during the worst of the winter wave.
Data from the early in the pandemic reveals there’s a “sweet spot” where infections can be reduced while keeping business steady. That magic number: around 20 percent.

Meanwhile, these businesses would lose just 42 percent of their visits, on average, according to research from scientists at Stanford and Northwestern. mehr hier
