Why should we care about infectious disease?

The goal of this unit is to improve students’ understanding on the impact that infectious diseases had and still have on societies, and to introduce the factors responsible for infectious diseases. The unit begins by engaging the students by presenting the impact of infectious diseases from historical and current perspective. It continues with introduction to microbes as the infectious agents and focus on their structure and functions, especially in relation to microbes’ infectivity and pathogenicity. The unit is completed by introducing the roles of different protective barriers that the human body has to fight off invaders.
