Please answer each part separately ( part 1 then part 2 as a separate question)
Part 1
Introduction: This week, you were introduced to how epidemiologists and public health practitioners collect disease information. The two main avenues are passive and active surveillance. Each has its own unique advantages and disadvantages. Additionally, due to the natural history of disease one option may be preferred over another. Your goal today is to explore the 2 surveillance systems that are in place to assess your selected community health issue.
Initial Post: Please consider the public health issue you have selected for your portfolio project. What state or federal systems are currently in place to collect information on this health issue?
