Which of the following is not a major criterion of the Jones criteria when diagnosing rheumatic fever? QID: 3741215Mark For Review Myalgia Carditis Subcutaneous nodules Chorea

The correct answer is Myalgia.

Explanation:
The Jones criteria are a set of guidelines used to help diagnose rheumatic fever, which is a complication of untreated streptococcal throat infection. The major criteria include:

Carditis: Inflammation of the heart, which may involve the endocardium, myocardium, and pericardium.
Chorea: Involuntary movements or jerking of the limbs and face.
Subcutaneous nodules: Painless lumps found under the skin, often over bony areas.
Erythema marginatum: A specific type of rash.
Polyarthritis: Inflammation of multiple joints.
Myalgia, or muscle pain, is not included as a major criterion in the Jones criteria for diagnosing rheumatic fever, although it may occur in patients with rheumatic fever, it is not one of the key diagnostic criteria.
