Do parents have to inform us if their child has hepatitis or hiv positive?

I have worked with a lot of HIV pos. kids but in the US at least- parents do not have to disclose the HIV status of a child. HIV at least, is fairly difficult to contract- in the sense that is not airborne and is not spread through casual contact. In fact a lot of health agencies here are classifying it as a chronic rather than a fatal illness now.
