We first reported the incidence of rheumatic fever (RF) surveillance Guangdong, Hainan from 1986 to 1990 5 to 18-year-old RF susceptibility of natural populations of new onset RF real incidence, an average of 20.28 / 100000. Compared with 1980, school-age children’s RF showed a significant downward trend. RF incidence of age, area, urban and rural areas and seasonal differences. Different from the previous reports at home and abroad, the incidence of RF in southern rural areas is obviously higher than that of cities. Different from 1980, the prevalence of RF type is more common in articular types and heart type is significantly reduced, showing lesser lesions. Including 4 towns in Sanya and Panyu Table 6 Comparison of prevalence rates of rheumatic fever among primary and secondary school students aged 5 ~ 18 in Guangdong aged from 5 to 18 years * Average annual living expenses of residents <1600 yuan Average annual living expenses of residents> 1600 yuan Table 7 Guangdong Hainan Province, different economic conditions Rural students aged 5 to 18 years of 1986 to 1990, the incidence of rheumatic fever compared to 5. RF Mortality: Follow-up RF patients for 4 years (2 to 47 months), an average of 19 months each without death. Second, the clinical manifestations of ARF: 64 cases of multiple arthritis (79%), 14 cases of heart inflammation (17.3%), chorea, subcutaneous nodules, annular erythema in 1 case. Cardiac function in patients with heart disease are I ~ II level, no heart failure or death. Third, RHD prevalence and the new detection rate 5 years, the diagnosis of RHD120 cases, the average annual prevalence of 0.59 ‰ (Table 9), of which the prevalence of 6 to 14 years decreased year by year Table 8 Guangdong, Hainan 5 ~ 18 Aged primary and secondary school students from 1986 to 1990, the distribution of rheumatic fever in each month Table 9 wide?
