Summary of major and minor criteria of RF in low-risk and moderate- to high-risk population.

Major criteria
Low-risk population	Moderate- to high-risk population
- Carditis (clinical or subclinical)	- Carditis (clinical or subclinical)
- Arthritis (polyarthritis only)	- Arthritis (polyarthritis, polyarthralgia, and/or monoarthritis)
- Chorea	- Chorea
- Erythema marginatum	- Erythema marginatum
- Subcutaneous nodule	- Subcutaneous nodule
Minor criteria
Low-risk population	Moderate- to high-risk population
- Polyarthralgia	- Polyarthralgia
- Fever (≥38.5 °C)	- Fever (≥38.0 °C)
- Elevation of ESR (≥60 mm in the 1st hour) and/or CRP ≥3 mg/dL	- Elevation of ESR (≥30 mm in the 1st hour) and/or CRP ≥3 mg/dL
