suspected case (of a disease)
Medical term used when a patient shows symptoms that suggest a particular disease but a definitive diagnosis has not yet been made.
He was isolated as a suspected case of the new influenza.
A definitive diagnosis cannot be made at the suspected-case stage.
Compound of 疑似 (giji, 'pseudo-; suspected') and 症 (shō, 'symptom; condition'). The term is used in medical contexts to describe a case that appears to be a particular disease but lacks confirmation.
