Tuberculosis (TB) has remained a public health problem worldwide including Thailand for decades. It is known that TB is one of the leading causes of death from a single curable infectious disease. The core strategies to combat TB recommended by experts include early case detection and proper treatment, along with infection control in the community. Currently Thailand has launched a policy of chest x-ray as a first line investigation for people at high risk of TB, primarily aiming to detect more TB cases earlier. There is always a question of how cost effective it would be to implement chest x-ray as a first line investigation. The objective of this study is to use a statistical model as a tool to determine the area with high risk for TB transmission, with a rationale to narrow down the area to ensure cost-effectiveness of the program. Results show that Tam-Malang Sub-district has a very high risk of tuberculosis transmission, with very high-risk score obtained from a risk matrix evaluation. Therefore, Tam-Malang Sub-district may be suitable for the implementation of active case finding method using chest x-ray as this strategy will greatly reduce the workload from performing sputum culture examination.
