(CNN) 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 Centers for Disease Control and Prevention. "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 tests were administered at 11 different health care facilities across 10 US states: California, Colorado, Maryland, Massachusetts, Minnesota, North Carolina, Ohio, Tennessee, Utah and Washington. Forty-two percent of the adults who tested positive, the data showed, reported having close contact with at least one person known to have Covid-19, compared with 14% of those who tested negative -- and most of the close contacts, 51%, were family members.
