Episode Summary

Differential Diagnosis and Testing Logic

This draft keeps each case tied to a concrete supported symptom, diagnosis, exposure, procedure, treatment decision, public-health action, or care-process risk. Educational differential details should be expanded only after transcript review.

The main diagnosis, exposure, injury, or care-process issue is plausible at the recap-supported level. The largest limitation is television compression of testing, consent, consultation, quarantine procedure, documentation, and follow-up.
