• The period before the onset of the disease
• Exposure might be there but disease has not take place yet

• Pre clinical
• Pre exposure
• Clinical 
• Resolution 

• Risk factors might be present
• Susceptibility 

• The probaility of an advirse event

• Primary 
• Secondary 
• Tertiary 

Early detection and prompt treatment of disease for cure, to slow progression, to prevent complications, or to limit disability to reduce prevalence. 

This is where we intervene so things dont get worst 

• Looking at disease population vs non disease population 
• Retrospecitive (looking back in time)

• Looking at differences when one group gets the treatment and the other dose not 
• Retrospective (looking into the future)

• When you monitor a group of individuals and see when disease occurs 
• Prospective (looking into the future)

• Those behaviors in which one engages with specific intent to prevent disease, to detect disease in the early stages, or to maximize health within the constraints of disease 

• Attain high quality, longer lives free of preventable disease, disability, injury, and premature death
• Achieve health equity, eliminate disparities, and improve the health of all groups
