Detecting and containing infection clusters and controlling community transmission is vital to alleviating the impact of the COVID-19 pandemic on human health. Isolating affected populations and restricting social interaction, travel, and the intermixing of people have long been used as remedies to the spread of contagious illnesses. Today, local, state, and federal initiatives are using similar approaches with cutting edge technology to gather and share data and decrease the toll of COVID-19. Public health officials need quick and accurate information to identify cases and they control transmission using strong, clear, and effective communications.
