CDC-INFO agent remotely handles COVID-19 inquiries from the public.
Human Connection

On March 2, 2020, CDC-INFO – CDC’s national contact center – became a 24/7 service and in the first month, agents handled over 34,000 calls and close to 57,000 emails about COVID-19. Over time, the number of agents surged from 50 to 500, and the average number of calls per day jumped from 900 to more than 1,600. Daily emails doubled. Agents are often the first to identify information gaps as they hear directly from the public where misinformation and confusion exist. CDC-INFO custom reports identify information gaps and misinformation and CDC-INFO staff work with CDC experts to update the tools that agents need to do their jobs well.
