What is swine flu, and tell me not to worry

I was online reading newsday and saw the swine flu headline. I have heard some people talking about it... what is it?

And then I read this:

In the Amityville flu outbreak, about three dozen students and three teachers at Edmund W. Miles Middle School had to leave school over the course of two days earlier this month after coming down with a mild respiratory illness or strep throat. "The individuals feel fine," Chaudhry said. "It's a precaution to determine if what we're dealing with is garden variety influenza, or something else."

I am in that school weekly for a behavior consultation. I shouldn't worry, right?

no, JMO but don't worry yourself over this.
