OK. I get that. But my question would be about HIPPA. She had a medical test, how does the school know the result? How do the police know the result? They shouldn't know anything and they should not be in a position to say "She's not sick, her test was negative".
I'm not sure, but maybe she basically said "My test was negative, but I still think I have COVID-19" I really can't see that as inaccurate or illegal.
When the administrator called the hospital and asked how many active cases of Covid-19 there were in the county and the hospital said zero, the administrator knew the girl was in error based upon the faulty test given.
