RIVERSIDE (CNS) - The County Administrative Center in downtown Riverside and other county buildings will close to the public starting next week, officials said today, citing an uptick in coronavirus infections and a spike in hospitalizations associated with COVID-19."Virtual methods have been long-standing and efficient ways to conduct business with the county. As one of the largest employers in the area, the county family is dedicated to providing high-quality services in a safe manner for our employees and visitors,'' County Executive Officer George Johnson said."Departments have diligently worked to add these safeguards to workspaces, including providing more telecommuting options. Returning to virtual means is one way the county is slowing the spread of the disease," he said.
