I'd like to know what exactly "They" means in that context.

We cannot know because the reference is to an unseen part of the text. In other words, we need to see more context (the other sentences that go with this one).

It's quite likely "they" means the people who live there. Of course, we can't know where "there" is without more context.

 

[jutfrank]

Yes. And there means 'the place where they live'. :-D

 

[GoesStation]

And there means 'the place where they live'. :-D

Which closes the loop nicely.

1. I'd like to know the difference in meaning between the yellow and blue parts.
2. I'd like to know why "to" is being used here.

Where did the blue part come from?

 

[GoldfishLord]

I've made it up.

 

[5jj]

Then your question would have been better as "Can we delete the to?"

The answer would have been "No".

 

[GoldfishLord]

I'd also like to know the reason why the "to" can't be deleted.

 

[jutfrank]

Reference in the sense I used it is a relationship (A refers to B), so it needs a preposition to connect the two related things. The word They refers to an unseen part of the text.

They still get cases of typhoid there.

It sounds like there are still cases of typhoid to me,
