If you caught COVID-19, you likely ate at a restaurant, CDC report finds
A new report by the CDC has linked COVID-19 cases to dining at restaurants.
In a completed in July, the CDC analyzed symptomatic outpatients from 11 U.S. health care facilities and found that adults who became infected with COVID-19 had reported dining at indoor or outdoor restaurants two weeks before getting sick.
“Adults with positive SARS-CoV-2 test results were approximately twice as likely to have reported dining at a restaurant than were those with negative SARS-CoV-2 test results,” the CDC wrote.
One of the limitations to the study is that participants didn't distinguish between indoor and outdoor dining.
For the study, 154 symptomatic adults formed the case-patients and had tested positive for COVID-19. They were then compared to control participants, which included 160 adults who were symptomatic outpatients from the same health care facilities with negative test results.
According to the report, there weren’t significant differences observed between the groups when it came to participating in activities that didn’t include going to a restaurant. They included: retail shopping, gyms, salons, using public transportation, gatherings of 10 or less in a home, going to an office setting, or going to a bar or coffee shop.
So, why the discrepancy? The big culprit was the use of masks.
“Exposures and activities where mask use and social distancing are difficult to maintain, including going to places that offer on-site eating or drinking, might be important risk factors for acquiring COVID-19,” the CDC wrote. “Masks cannot be effectively worn while eating and drinking, whereas shopping and numerous other indoor activities do not preclude mask use.”
The CDC added that reports of exposure in restaurants have been linked to poor air circulation where direction, ventilation and intensity of airflow might affect the transmission of the virus, even if restaurants are following .
“As communities reopen, efforts to reduce possible exposures at locations that offer on-site eating and drinking options should be considered to protect customers, employees, and communities.”
In San Francisco, restaurant patrons are whenever they wait to be seated, leave the table or when a server takes their order. Masks are not required only when eating or drinking. But even as restaurateurs have adapted to the new normal, regulating mask usage is a complicated dance between being hospitable and following safety rules.
"There’s not enough money to have five extra staff just lifeguarding everybody to have a mask on between every bite," Ben Bleiman of Tonic Nightlife Group and the San Francisco Entertainment Commission told last month. "We’re not kindergarten teachers. We’re really good at making people follow the rules, but asking somebody to do something seven times is really hard when it doesn’t rise to an egregious error."
