Answer:
I am not completely sure what you are asking. But here is my best shot.
During - time, it tells what is happening while
the - is a preposition
epidemic - what is happening (relates to the first question)
early - when it is happening
warnings - the noun/subject
widely - where it is going
This is a standard form of speech.
I don’t understand what you’re trying to ask?
continue dude or do u need the answer after the word he like what he did or say?
