During the 1960s, the incidence of acute rheumatic fever ranged from 23 to 55 per
100,000 urban children aged from 2 to 14 years in the United States.Currently, it is less
than 2 per 100,000 with a prevalence of rheumatic heart diseases of less than 1 per 1,000
school-aged children. In the past, the attack rate of rheumatic fever caused by
streptococcal infections was about 3% in military population and 0,3 % among school
children. In the United states today, the attack rate may be much lower,but valid data are
not available. In 1984 WHO committee of experts in massive prevention of
cardiovascular diseases and struggle with them noticed that rheumatic disease morbidity
decreased in developed countries, but the disease remains a main cause of cardiovascular
disease mortality in population aged below 40 in most developing countries.The study
was carried out among 400 school children aged 10-16 of Ulaanbaatar city in order to
determine the prevalence of the streptococcal tonsillitis, rheumatic fever and
cardiovascular disease cause by rheumatic fever by using questionnaire and streptococcus
latex assay. Conclusion: We studied the pharyngotonsillities related with the B-hemolytic
of A group among the children in school which is located in the center of Ulaanbaatar
city. The prevalence of streptococcal pharyngotonsillitis was 15,08%. Because of
insufficient contact to doctors ( 46.7 %) when they got streptococcal infection, large
number of episodes in a year (43.3%), incomplete treatment of tonsillitis(40.0%)
becomes inflamed and transferred to the chronic stage. The research among the school
children of "ger" or tent district school to analyzing the streptococcal pharyngotonsillitis
was 50.25%. The half of children in suburban district has a streptococcal
pharyngotonsillitis due to the treatments insufficiently contact to doctor (53.5%) when
they having sore throats and infecting of streptococcus.Also can be influenced to the
suburban area, living condition, social level, and parent's education.
