Adults who tested positive for Covid-19 were approximately twice as likely to have reported dining at a restaurant in the 14 days before becoming ill than those who tested negative, according to a new study from the US CDC. "In addition to dining at a restaurant, case-patients were more likely to report going to a bar/coffee shop, but only when the analysis was restricted to participants without close contact with persons with known COVID-19 before illness onset," the researchers wrote. The study, published on Thursday, included data on 314 adults who were tested for Covid-19 in July because they were experiencing symptoms; 154 tested positive and 160 tested negative.
