DISCUSSION
F r o m the foregoing charts and table it can be seen that there has been an appreciable reduction in the incidence of rheumatic fever in San Francisco children from 1946 t h r o u g h 1955. This m a r k e d decrease in the n u m b e r of cases of active rheumatic fever was not paralleled b y a similar decrease in the n u m b e r of cases of recurrent rheumatic fever from 1949 to
1954 active

in convalescent homes with the diagnosis of rheumatic fever, but in 1955 there were only seventeen such cases. The m o r t a l i t y rate from rheumatic fever in San Francisco has never been high. I n 1949 there were five children r e p o r t e d as dying f r o m rheumatic f e v e r or its complications.

T h r o u g h the utilization of an active R h e u m a t i c F e v e r R e g i s t r y which m a i n t a i n s a c u r r e n t r e p o r t of all cases of active r h e u m a t i c f e v e r rep o r t e d in the City a n d County of San Francisco in children up to the age of 21 years, it has been n o t e d t h a t there has been an appreciable decrease in the n u m b e r of active rheumatic f e v e r cases f r o m 1946 t h r o u g h 1955, an i n t e r v a l of ten years. This has been a c c o m p a n i e d b y a decrease in the n u m b e r of children who were hospitalized or were p l a c e d in convalescent homes w i t h this condition d u r i n g these years, and p a r t i c u l a r l y f r o m 1949 on. A t the same time it was n o t e d t h a t the n u m b e r of cases of r e c u r r e n t r h e u m a t i c f e v e r remained r e l a t i v e l y high until 1954 when, a f t e r an e d u c a t i o n a l c a m p a i g n for physicians a n d l a y persons and with the a v a i l a b i l i t y of p r o p h y l a c t i c drugs t h r o u g h the C r i p p l e d Children Services P r o g r a m , there was an appreciable drop which m a i n t a i n e d itself through 1955. C0/NCLUSION
An analysis of the statistics maintained b y a R h e u m a t i c F e v e r Regist r y i n s t i t u t e d b y the San Francisco H e a r t Association a n d m a i n t a i n e d b y the San F r a n c i s c o D e p a r t m e n t of Public H e a l t h indicates t h a t there has been a decrease in the incidence of r h e u m a t i c f e v e r in S a n F r a n c i s c o school children. T h e r e has been a m u c h slower decrease in the n u m b e r of cases of r e c u r r e n t r h e u m a t i c fever, but a p p a r e n t l y since the a d v e n t of a c a m p a i g n of education of physicians
279
and p a r e n t s r e g a r d i n g the use of penicillin or sulfa d r u g s for the prevention of these recurrences, as well as the increased a v a i l a b i l i t y of these drugs through a program originated b y the State of California Crippled Children Services, t h e r e has been an appreciable decrease in the n u m b e r of r e c u r r e n c e s as well. Thus there has been a decrease in the incidence of a disease which at one time was considered to be the most common cause of d e a t h in children between the ages of 5 a n d 15 years. ' R h e u m a t i c f e v e r is a p p a r e n t l y b e g i n n i n g to assume a m u c h less i m p o r t a n t role not only in m o r t a l i t y b u t in morbidity, as evidenced b y the above figures. However, the p r o b l e m s involved in the recognition of r h e u m a t i c f e v e r are still great, its m a n a g e m e n t has still not been stabilized, a n d there m u s t be no diminution in the measures necessary to suppress this disease. I wish to t h a n k XVilss Ruth Rieve for her help in the p r e p a r a t i o n of this paper. REFERENCES 1. Robinson, S. J., Aggeler, D. M., and Daniloff, G.
