Introduction

In this study session, you will learn about the major vaccine-preventable diseases that are caused by viruses, how they are transmitted, and how they can be prevented and controlled. Knowing the signs and symptoms of these viral diseases will help you to identify them in your community, so that you can refer infected people quickly for treatment at a nearby health facility.

Greater understanding of viral vaccine-preventable diseases will also enable you to explain to parents why they should have their children vaccinated to prevent them from susceptibility to these viruses.
