Three UC Berkeley health experts discuss recent reports of employee COVID-19 infections at Berkeley Bowl, Whole Foods and other local businesses. "As long as customers are wearing a mask and staying more than six feet away from employees (who should also be wearing masks), they should be safe," said UC Berkeley public health professor John Swartzberg. UC Berkeley public health professor Arthur Reingold seconded Swartzberg's assessment of indoor transmission, adding that stores with infected employees should communicate with Berkeley's Public Health Division to decide appropriate cleaning procedures and whether to close. "Transmission is mostly a risk with prolonged indoor contact, and much less likely with brief customer-employee encounters," Reingold said. "There might be a better case to be made about possible transmission to other employees who interact frequently in the store." UC Berkeley public health professor Malcolm Potts stressed the importance of following the Centers for Disease Control and Prevention's guidelines in order to prevent COVID-19's spread. Potts also believes that Alameda County and the Berkeley Public Health Division should follow California Gov. Gavin Newsom's guidance regarding business closures.
