Status Updates From The World’s Deadliest Plagu...

I've reached the chapter "The Black Plague" and I'm noticing, not for the first time, that there is content that has been copied word for word from a previous chapter. I understand that some of these plagues are very similar and may have, in fact, been variants of the same disease; however, it seems just plain lazy that they simply used the same exact excerpts across multiple sections.
