Epidemiological report

Pick one group and write an epidemiological report to a policymaker (a state senator) properly using all concepts in the group. You must pick one to four exposures and one to four health issues. Use them to articulate the report.
Make sure every concept is well understood by your senator (who is an expert on thrip identification in the mountains of the South of Chile) by using examples or your own very simple definitions.
Every time you use a concept add (between parentheses) the concept. Example: According to this, we should do an experimental study in which we have two randomized groups: people receiving the treatment and others just being controlled (experiment).
When I see (experiment) I will know what concept you are presenting and will evaluate whether it is properly used and adequately explained. As you see, I did not need to use the word experiment in my report. I just add it for grading purposes.
