"My initial reaction is flu. "

That was what Brock Waterman thought about a week ago while he was studying abroad in Mexico.

Since then he's changed his tone a little.... and is now back in Boscobel in southwestern Wisconsin.

" Where I was at in the semester it just didn't seem like it was worth sticking around for."

The UW-Platteville junior was in Guadalajara about 200 miles from where the swine flu first appeared in Mexico City.

But he didn't hear about it until he spoke to his parents last Thursday.

"I think our big concern was that if they close the border and then he got sick and then we couldn't go down there, he couldn't come here."

Brock and his parents didn't discuss bringing him home until Sunday night.

But once he found out classes were cancelled at the university on the following Monday and Tuesday, the decision became a no-brainer.

" That was the point I was like this is no longer fine. There's actually problems."

Waterman wasn't due back for another three weeks.

But with the situation worsening, he jumped on the next plane and headed home.

"When I came through the airport I had a bandanna that I had over my mouth and then I was just washing my hands like mad for the whole trip home."

The trip may have been scary. But, his parents say they're glad he's home.

"Wonderful. Best decision he ever made I believe coming home."

Waterman says he's still in contact with friends in Mexico.

There haven't been any cases of swine flu in the area he was staying.
