Which factor is used to estimate prognosis?

• A. Usual course of the disease and individual characteristics.
• B. The weather.
• C. The hospital location.
• D. The patient’s hair color.

Answer: (B)

Prognosis is estimated from how the disease typically progresses and how the individual patient factors influence that trajectory. The usual course of the disease provides the baseline expectations for progression and outcomes, while patient-specific characteristics—such as age, overall health, functional status, disease stage, comorbidities, and relevant biomarkers—modify that outlook. External variables like weather or hospital location do not determine the biological course of a disease, and hair color has no relevance to prognosis.
