Surveillance and Rapid Needs Assessment During Disasters

According to the Centers for Disease Control and Prevention (2012), "...it is important to conduct surveillance to determine the extent and scope of the health effects on the affected populations...Public health surveillance during a disaster allows for the detection of potential disease outbreaks and track disease and injury trends."  In public health emergencies, decisions need to be made in a very short period, which is very different than a standard epidemiological investigation.
