mysterious illness
Undiagnosed medical condition
A mysterious illness is a medical condition whose cause, nature, or origin remains unknown or unexplained.
The phrase typically describes ailments that baffle doctors or resist diagnosis: Dozens of diplomats reported a mysterious illness while stationed abroad.
It often carries undertones of intrigue or concern, suggesting something potentially sinister or unprecedented rather than merely undiagnosed.
