No. HIPAA is about sharing PHI between covered entities. P stands for Portability. Unless Jenny is working in one of those covered entities and Jenny's boss learned about her covid and pregnancy by pulling PHI - then no, it's no under HIPAA.

Her boss doesn't have a duty to keep it private in any legal sense. Jenny can ask not to tell anyone, but legally, it doesn't matter.

To clarify, the P in HIPAA is "portability", in PHI it's "protected". Confusingly there's also PII where it's "personally".
