Transient remission of juvenile rheumatoid arthritis after measles

A 4-year-old Japanese girl with systemic juvenile rheumatoid arthritis had an attack of measles. On the day following the first signs of measles she became afebrile and free of joint pain even though aspirin therapy was discontinued. The remission lasted for 10 days. It appears that the measles virus infection may have been responsible for the brief remission in this patient. The observation of a remission of juvenile rheumatoid arthritis after measles is extremely rare.
