LESSON PREVIEW/REVIEW 1) Introduction (2 mins) In an animal disease outbreak, efforts to contain and control the spread of disease will be essential. It is thereby fundamental to have understanding of how diseases can move from one animal to another, as well as location to location; these are called routes of transmission. Animals can be exposed to disease agents from a variety of sources. Most occur between animals, but transfer can also occur from the environment, such as soil, water, or feed. Some diseases can be shared between of animals and people. Animal diseases that are transferred to people are referred to as zoonotic diseases, while diseases of humans transferred to animals are referred to as reverse zoonoses. This lesson will present an overview of the routes of disease transmission and aims to develop critical thinking to preventive measures that can be used to break the transmission cycle.

State the possible horizontal and vertical transmissions of the agent causing the following diseases. Place “NOT POSSIBLE” where transmission is not applicable.
