Surveillance and epidemiological monitoring of conditions and infections help public health programs in the following areas:

• Identify target populations most affected
• Identify outbreaks or changes in trends
• Use data to drive policies and programs
• Allocate resources to maximize limited resources
• Plan for future direction based upon epidemiology changes
