Topic overview

Start with the big picture

Infectious disease epidemiology examines patterns and processes related to infectious diseases. Modes of transmission is identified as a topic within this chapter, but the supplied source contains no headings, key points, or representative excerpts that describe particular transmission routes. This preview therefore does not specify mechanisms or examples. The full lesson is the place to explore the topic in greater depth; consult its explanations for the specific concepts and structure covered. Use this introduction as a guide to the topic’s place in the chapter rather than as a detailed account of transmission.
