While public health surveillance has traditionally focused  on infectious   diseases, public health officials are now targeting environmental  issues,   occupational matters, injuries, chronic diseases, birth defects, risky  health   behaviors, and genetics. It is for this reason that statistical data has    become  vital for public health officials, and why for public health officials,    it is  important to be able to use and interpret data.

For the Unit IV Case Study, research the sources of data in  your community,   and address the following points.

1. Briefly describe your local sources of data used  by public health        officials.
2. Discuss one strength and limitation of  collecting data in your        community.
3. Describe an intervention or program to address a  public health issue in        your community. Provide an example of how data was  interpreted to the local        community in the intervention or program. Please  provide a link to the        intervention or program.
