What is the role of epidemiology in disease prevention?

• Accurate purpose statement.
• Techniques to be implemented for collecting and analyzing research.
• The method applied for analyzing collected details.
• Type of research methodology.
• Probable objections for research.
• Settings for the research study.
• Timeline.
