Which of the following Jones criteria is required as the only sole criterion to diagnose acute rheumatic fever (RF)?
ExplanationThe diagnosis of acute RF can be made without strict adherence to the Jones Criteria in 3 circumstances: (1) when chorea occurs as the only major manifestation of acute RF, (2) when indolent carditis is the only manifestation in patients who first come to medical attention only months after the apparent onset of acute RF, and (3) in a limited number of patients with recurrence of acute RF in particularly high-risk populations.
