Redding health officials are offering some reminders as people head inside for the cold weather. Health Officer Doug Hartline says both COVID-19 and seasonal flu have symptoms are similar, and both can spread to others and cause serious illness. Anyone who has any of these symptoms should stay home until fever free for 72 hours, symptoms are improving and it's been at least 7 days since symptoms started. Hartline says staying home helps prevent the spread. Measures to help prevent the spread of COVID and flu includes washing hands often, and avoiding touching eyes, nose, and mouth with unwashed hands.
