Subclinical disease among people with culture-confirmed pulmonary tuberculosis in Singapore - a retrospective study

Our study suggests that subclinical TB are more likely to occur in those older than 70 years and those with immunocompromising conditions. The use of diagnostics such as chest X-ray and sputum TB PCR are helpful in diagnosing subclinical TB. Further research is necessary to evaluate other screening tools in detecting these early disease states.
