Invasive Disease

Invasive Disease

Brief Description:
Invasive diseases can be caused by a number of infectious agents. Global trade and travel have enabled serious invasive species to create epidemics that led to pandemics beginning in the middle ages and continuing to today. This lesson focuses on the infective agents, how they act and the methods we use to prevent and control them. It provides insight into diseases that affect plants, animals, and affect the food supply in addition to those that have a direct impact on people.

Objectives: By the end of this unit the students will be able to:

  1. Identify agents that cause disease;
  2. Describe how global trade and travel, both yesterday and today, introduces invasive species such as diseases; and
  3. Explain how an epidemic becomes a pandemic and give an example of one;
  4. Explain methods to control, contain, and/or treat infectious diseases.
