ORPHA:3099Disease

Also called Acute rheumatic fever

What it is

Rheumatic fever (RF) is a multisystem inflammatory disease occurring as a post-infectious, nonsuppurative sequela of untreated streptococcus pyogenes (Group A streptococcus [GAS]) pharyngitis, and mainly occurs in individuals aged 5 to 15 years. The most common presenting signs are fever, migratory polyarthritis and carditis.

Disease

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.
