I hear you, but you're going to have a tough time convincing a Florida jury that having a baby in your hands 6 months after getting married is Hipaa protected "medical information", but icbw.
I just checked and yes, it's HIPAA that covers such a case. If the teacher didn't sign a release saying it was okay to publish/disclose the information, then the school is on the hook for doing so.
It's funny watching CSI-type shows with my wife, she's always pointing out which doctors and nurses would be ****canned and sued in the real world for disclosing medical info to the cops.
