3. Agent
What is web of causation?
It considers all the predisposing factors of any type and their complex interrelationships with each other
Natural history of disease
It signifies the way in which a disease evolves over time from the earliest stage of its PATHOGENESIS phase to its termination as recovery in absence of treatment or prevention
How is natural history of a disease well established by
Cohort study
Phases of natural history of a disease
1.prepathogenesis
2.pathogenesis
Prepathogenesis phase
Period before the onset of disease in man
Prepathogenesis phase is also known as
Man in the midst of disease or man exposed to the risk of disease
PATHOGENESIS phase
It begins with the entry of the disease agent in the susceptible human host
How is the PATHOGENESIS phase modified
