What is disease transmission cycle?

2.1 Introduction to the transmission cycle of disease This cycle can be simple, with a direct transmission from current to future host, or complex, where transmission occurs through (multiple) intermediate hosts or vectors. This cycle is called the transmission cycle of disease, or transmission cycle.
