Human case
Cold, Flu, or Something Else?
Several people in one home feel tired and headachy, so the first guess might be a routine seasonal illness. This starter DxDetective case asks you to slow down, compare who feels worse, where symptoms change, and which clues make the household pattern matter. You play from a caregiver's point of view and choose what to check before making the final call. The public setup shares the home setting, intro difficulty, skill focus, and decision pressure without naming the hidden cause or safest final action. Use it to practice pattern recognition, household observation, and escalation judgment while the answer stays hidden until play. The goal is not to diagnose a real family; it is to practice noticing when a familiar explanation is not enough.
