What does pestilence mean as it is used in the following lines from Act V, Scene 2 of Romeo and Juliet?

"And here I stand, both to impeach and purge,

Myself condemned and myself excused.
Then, prince, I say, and now I tell theem here,
That through this violet transgression of thine,
Myself, thee, and thyne are all ouerthrown."

In this context, pestilence means a deadly disease or plague that causes widespread destruction and death.
