Revised 2015 Jones criteria for the diagnosis of acute rheumatic fever (ARF) based on population-risk
| Low-risk populations | Moderate / high-risk populations | |
|---|---|---|
| Major criteria | Migratory polyarthritis | Migratory polyarthritis/monoarthritis |
| Carditis | Carditis | |
| Chorea | Chorea | |
| Erythema marginatum | Erythema marginatum | |
| Subcutaneous nodules | Subcutaneous nodules | |
| Minor criteria | Polyarthralgia | Monoarthralgia |
| Fever ≥38.5°C | Fever ≥38.0°C | |
| ESR ≥60 mm/hour and/or CRP ≥30 mg/L | ESR ≥30 mm/hour and/or CRP ≥30 mg/L | |
| Prolonged PR interval on ECG | Prolonged PR interval on ECG | |
| Evidence of GAS infection | Positive throat culture | |
| Elevated/rising ASO titre | ||
| Positive rapid streptococcal antigen test | ||
Low-risk population is defined as an ARF incidence ≤2 per 100,000 school-aged children or ≤1 per 1000 population per year. For a diagnosis, two major criteria or one major and two minor criteria must be fulfilled in the presence of a recent group A streptococcus (GAS) infection.4
ASO = antistreptolysin O; CRP = C-reactive peptide; ECG = electrocardiogram; ESR = erythrocyte sedimentation rate
