Unintended consequences often occur due to the complex nature of public health systems and human behavior. Some common reasons include:
Behavioral Changes: People might change their behavior in response to health interventions in ways that were not anticipated. Ecological Interactions: The introduction or removal of one element in an ecosystem can have cascading effects. Resource Allocation: Focusing resources on one health issue might inadvertently neglect other critical areas. Policy and Governance: Policies designed with limited input from affected communities can result in resistance or non-compliance.
