This woman is a pain

I work with a boy in a school. The teacher has a lot of complaints about the fact that this child requires a lot of care that she does not understand and I do not explain. I am there to keep this child alive not give her health information that I can not disclose (or do not want to). The other day just pushed me over the edge. This child was okay (but not perfect) in the morning but later in the day he needed to go home (the reason is not important). The teacher was told his parent was coming and she rolled her eyes and said "was he sick this morning?" I explained that the parent was called and told problem and decided to come and pick child up. This seemed to irritate her as usual. I feel that HIPPA says I can not give certain info and if she really wants to know to call parents and risk being chewed out for questioning me since the parents do not take kindly to it. My company does not want to get involoved (as usual). Does HIPPA cover this in that I can not disclose his medical information?
