Overview and General
Surveillance, monitoring and tracking disease outbreaks helps health officials allocate resources effectively and efficiently. Epidemiologists use monitoring data to predict where and how disease might spread. It is important to know where disease outbreaks not only begin in the world, but also how and where they might spread in the United States. A primary goal of flu monitoring is to identify any outbreak of human-to-human transmission quickly so health officials can attempt to contain and control the outbreak.
