Natural History Of Disease

When evaluating the effectiveness of a drug in a clinical trial, it is important to consider the natural history of the disease.

The natural history of a disease refers to the course that the disease takes in the absence of any treatment.

✶Natural History of Disease Timeline:

Principles of Epidemiology | Lesson 1 - Section 9 (cdc.gov) (CDC Principles of epidemiology, 2nd ed.)

This includes the progression of the disease, the symptoms that are experienced, and the outcomes that are typically seen.

[S]ubclinical disease, extending from the time of exposure to onset of disease symptoms, [includes] the incubation period…and the latency period.

The latency period for leukemia to become evident among survivors of the atomic bomb blast in Hiroshima ranged from 2 to 12 years, peaking at 6–7 years.

By understanding the natural history of a disease, researchers can better determine the impact that a treatment is having on the disease, and whether the treatment is having a beneficial effect.

A cohort study is the best way to identify…natural history of a disease…However, this type of study is less useful for examination of rare events or those that take a long time to develop

It is important to consider the natural history of a disease when designing a clinical trial, as this can help to ensure that the trial is adequately powered to detect any differences between the treatment and control groups.
