If the CDR target (70%) is achieved, the effect on TB transmission will be considerable. However, CDR remains a major obstacle to TB control. In this study, we compare factors related to case detection in high and low CDR area in Central Java, Indonesia. This was an observational, analytic study with cross sectional design. The study was carried out during 2012 in Surakarta City (high CDR area) and District of Sukoharjo (low CDR). Study subject was 29 health officers of tuberculosis control program, consisted of 17 persons from health centers in Surakarta City and 12 persons from health centers in District of Sukoharjo. Primary data was collected through interview using structured questionaire. The result showed characteristics of subject (age, sex, education) from high and low CDR areas did not differ significantly However, tuberculosis officer in high CDR areas has longer length of work comparing those in low CDR areas. Tuberculosis training given to tuberculosis officer influencing the higher CDR. Suspect detection in high CDR area is carried out both in health and non-health sectors. Active case finding was more prominent in high CDR area. Keywords: tuberculosis, case detection rate, suspect detection, active case finding I. INTRODUCTION Tuberculosis (TB) is one of the leading causes of morbidity and mortality worldwide, affecting one-third of world's population. Geographically, the incidence is much higher in Southeast Asia (India and China together account for nearly 40% of the global TB cases). 1 However, the prevalence and transmission of TB and other mycobacterial infections may be considerably reduced by early detection of the disease. 2 This may achieve by high number of case detection rate (CDR) of tuberculosis. CDR is ratio of the number of notified TB cases to the number of incidence TB cases in a given year. The World Health Organization (WHO) has formulated a case detection rate target of 70%. 3 If the target is achieved, the effect on TB transmission will be considerable. 4,5 However, despite a decade of success in improving cure rates for tuberculosis (TB), diagnosis and case detection remain a major obstacle to TB control. 6 Only five provinces in Indonesia achieved CDR target, while other 28 have not achieve it. Central Java is one of province remains under target. 7 In this study, we compare factors related to case detection in high and low CDR area in Central Java, Indonesia.
