What is the initial step in an environmental public health investigation?

The initial step in an environmental public health investigation is to conduct an investigation. This phase involves gathering preliminary information, which includes understanding the scope of the problem, identifying potential sources of exposure, and determining the populations that may be affected. This groundwork is crucial because it sets the stage for further actions, such as inspections or trials, which focus on confirming findings and implementing solutions.

Although inspections may follow an investigative stage to evaluate specific environments or conditions, they rely on the insights obtained during the investigation phase. Without this foundational step, any subsequent actions may lack the necessary context and focus, making an investigation essential for a structured approach to addressing public health concerns related to environmental factors.
