Analisis Hasil Pemeriksaan Spesimen Penderita Demam Berdarah Dengue di Jakarta, 1991

An analytical study was conducted of 885 serum specimens, from 14 different hospitals in Jakarta, that were submitted to Virology Laboratory at Communicable Disease Research Center, NIHRD, Jakarta, for dengue serology examination using HI test, in 1991. Only paired, acute and convalescence specimens, total of 689, fulfilled the criteria for the analysis. The positivity rate of these paired sera was 43,54%, which is slightly lower compared with 50,41 % that was observed in 1990. There was an increase in number of submitted specimens to the laboratory, starting from January, with two peaks in May and June, followed with gradual decline from July through December 1991. No significant difference was observed among sex of patients. The mode of age ofpatients were 5 - 15 years old, however sera from older patients (>= 60 years) were also submitted for examination. Factors which could influence those patterns: age, sex, seasonal variation, etc are discussed in detail in this paper

Gambaran Serologi Uji H.i. pada Penderita Demam Berdarah Dengue di Beberapa Rumah Sakit dan Laboratorium Kesehatan Wilayah Jakarta Tahun 1990

A serological study had been conducted on 1329 specimens collected from DHF suspected cases admitted to 18 hospitals in Jakarta during 1990. Analysis of data were done in 978 paired specimens including: sex, age, hospital origin. The clinical diagnosis accuracy for DHF from the whole specimens were 50,41% compared with 70,13% in 1986-1987. Number of DHF cases were fluctuating from January to September 1990 with three peaks in May, July, September. There was no sex difference. Mode of age group of DHF cases were 5-10 year old. There were also DHF cases among older age group (15-20). This finding confirmed the previous report and might be due to Dengue virus virulence differences and decreasing of endemicity
