I would say metonymy.
metonymy means "a figure of speech consisting of the use of the name of one thing for that of another of which it is an attribute or with which it is associated". ~Merriam Webster
Basically, it replaces one word with another one that has a similar meaning, or that it can be compared to.
Here are some examples from the passage:
1. diseases are compared to a traveling circus, because both travel far and quick.
2. germs are compared to carolers, because the "happiness epidemic" germ spreads merriment like carolers going from door to door.
I hope this helps you baiii <333
