Acute Rheumatic Fever: Revised Diagnostic Criteria.

The Jones criteria of 2 major criteria or 1 major plus 2 minor criteria that have been classically used to establish the diagnosis have been significantly modified in 2015 by the American Heart Association. The criteria now include the utilization of echocardiography and Doppler color flow mapping as diagnostic tools for carditis, along with defining criteria in relation to overall population risk, delineating low- versus moderate-high risk populations. Monoarthritis and polyarthralgia are now major criteria for moderate- to high-risk groups.
