## **Core Concept**
The Jones criteria are used to diagnose **Acute Rheumatic Fever (ARF)**, which is an inflammatory disease that can occur after a group A Streptococcus infection. The criteria are divided into major and minor criteria. The major criteria help in the diagnosis by identifying specific manifestations of the disease.

## **Why the Correct Answer is Right**
The Jones major criteria for Acute Rheumatic Fever include:
- **Carditis**: Inflammation of the heart.
- **Polyarthritis**: A type of arthritis that affects multiple joints.
- **Sydenham's chorea**: A neurological disorder characterized by rapid, irregular movements.
- **Erythema marginatum**: A rash with a distinctive appearance.
- **Subcutaneous nodules**: Painless lumps under the skin.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that the Jones criteria are essential for diagnosing Acute Rheumatic Fever. Remembering the major criteria can help in quickly identifying patients with ARF. The presence of two major criteria or one major and two minor criteria, along with evidence of a preceding streptococcal infection, is diagnostic.
