Study Notes
Disease Eradication
- When disease morbidity is very low, a "residual" infection remains in the population.
- This creates a state of equilibrium among the disease agent, host, and environment.
- Despite low morbidity, hidden infection foci, unrecognized transmission methods, and resistance in the vector or organism persist.
- These elements can re-emerge when the agent-host-environment equilibrium is disrupted.

Description
This quiz examines key concepts in disease eradication, focusing on the dynamics of residual infection, disease equilibrium, and the factors that can lead to the resurgence of disease agents. Test your understanding of how hidden infections and environmental changes can impact disease control efforts.
