On April 7, Chinese researchers published a paper that looked at 318 outbreaks with 1,245 Sars-Cov-2 infections. They found that 80 percent took place in homes or apartments. Another 34 percent occurred on public transportation (some outbreaks occurred in more than one place, or could not be placed at a single venue). All other venues, including stores and restaurants, accounted for less than 20 percent of infections combined. “Sharing indoor space is a major SARS-CoV-2 infection risk,” the researchers wrote.
