What do we call the bodies of evidence that indicate signs or symptoms of a disease in living organisms?

The term that is most commonly used to refer to the bodies of evidence indicating signs or symptoms of a disease in living organisms is "manifestations." This term encompasses both observable signs and subjective symptoms that collectively reflect the presence of a disease. Manifestations can be physical changes that are observable (like rashes or lesions) as well as non-visible indications that the organism is affected (like changes in behavior or internal functioning).

While "indicators" could imply a suggestion or hint of disease, it is not the standard term used in medical or biological contexts to describe the concrete evidence of disease. Similarly, "symptoms" specifically refers to the subjective experiences reported by the organism (such as pain or fatigue), while "signs" refers to objective evidence that can be observed or measured by a practitioner. Together, these terms provide a comprehensive understanding of how diseases present in living organisms, with manifestations capturing the full spectrum of those evidences.
