By the end of this module, you’ll be able to:

- List four categories of disease agent sources

- Discover conditions when disease transmission is likely to occur

- Describe the means of disease transmission in a given situation

Learners examine animations of the most common transmission signals used in automated systems, such as 4 mA to 20 mA, 3 psi to 15 psi, and 0 to 10 volts. A brief quiz completes the activity.

In this module, you'll be able to :

- Identify five routes of infection

- Describe how diseases are transmitted in animals

In this interactive object, learners read about the occupations that are most at risk for bloodborne pathogen exposure. They also read about the most common pathogens and how they are transmitted. This learning object is based on information from the U.S. Occupational Safety and Health Administration.

In this animated object, students view a depiction of how force is transmitted by hydraulic cylinders and confined fluid.

By the end of this module, you'll be able to:

- Identify actions that can reduce biosecurity risk

- Develop a biosecurity action plan for a farm

- Select the most cost effective strategies

In this interactive object, learners identify nursing actions that help to prevent the spread of infection.

Learners match the names of parasitic organisms to the diseases they cause and the modes of transmission.

In this learning activity you'll observe how switches are used in local area networks to increase data transmission speeds.
