Either, but/and it's a bad sentence.

Why are these sentences wrong?

There's only one sentence.
It's not wrong. It just sounds awkward.
One reason is that it shouldn't be necessary to say that a person is sick twice, once at each end of a sentence. But it's not easy to explain a subjective sense of awkwardness.
