Step 8: Hypothesis Evaluation – Environmental Health

By the end of this module, you should be able to:
  • Describe the roles and jurisdiction of environmental health and regulatory professionals in outbreak investigations.
  • Identify how different disciplines work together in the outbreak team and describe what each does.
  • Describe the three categories of contributing factors in an outbreak.

Now let’s look at hypothesis evaluation from the perspective of environmental health. Environmental health hypothesis evaluation often involves an environmental assessment with the goal of identifying contributing factors that may have led to the outbreak. In this video, we will discuss the differences between a routine inspection and an environmental assessment and describe some common contributing factors.
