❤️ Jones Criteria (Acute Rheumatic Fever, 2015)
UseWhen to use: suspected ARF when major/minor manifestations and GAS evidence are being assessed.
StrataClassification aid for initial ARF. Echo carditis counts as major in 2015 revision.
LimitsWhen not to use: as a substitute for full rheumatology/cardiology wor… · Pitfall: applying low-risk cutoffs in endemic high-prevalence regions. · Post-strep reactive arthritis and other mimics exist.

2015 AHA revision.
When to use
When to use: suspected ARF when major/minor manifestations and GAS evidence are being assessed.
How it works
Low-risk: 2 major or 1 major+2 minor. Mod/high-risk: also allows 3 minor. Plus preceding GAS (exceptions: chorea / indolent carditis).
Key points
- 2015 AHA revision.
- GAS evidence usually required.
- Next: echo / secondary prophylaxis.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| ARF prevalence setting | Low-risk population |
|---|---|
| Evidence of preceding group A strep (culture / rapid Ag / rising ASO-antiDNaseB) | No / pending |
| Major: Carditis (clinical and/or subclinical echo) | No |
| Major: Arthritis (poly in low-risk; mono/poly/polyarthralgia allowable in mod/high) | No |
| Major: Sydenham chorea | No |
| Major: Erythema marginatum | No |
| Major: Subcutaneous nodules | No |
| Minor: Fever (≥38.5 °C low-risk / ≥38.0 °C mod-high) | No |
| Minor: Arthralgia (poly low-risk; mono mod-high) — only if arthritis major absent | No / N/A |
| Minor: Elevated ESR/CRP (ESR≥60 low-risk or ≥30 mod-high; and/or CRP≥3.0 mg/dL) | No |
| Minor: Prolonged PR (after accounting for age; only if carditis major absent) | No / N/A |

FAQ
Frequently asked questions
- Does Jones Criteria (Acute Rheumatic Fever, 2015) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Jones Criteria (Acute Rheumatic Fever, 2015) calculated in practice? Can you show a worked example?
