Detailed explanation-1: -In most countries of low and middle income with a high burden of tuberculosis, investigation for tuberculosis usually only starts when people present to health services with symptoms suggestive of pulmonary tuberculosis, termed passive case-finding.

Detailed explanation-2: -Passive case finding is standard and consistent with the WHO-recommended Stop TB Strategy 2. Active case finding includes all methods for the identification and then treatment of those with TB who have not reported to the healthcare system of their own accord.

Detailed explanation-3: -Conclusions: Subclinical disease may limit the impact of current diagnostic strategies for TB. Active detection of undiagnosed prevalent cases may achieve greater population-level TB control than increasing passive case detection.

Detailed explanation-4: -Globally, national tuberculosis programmes rely predominantly on passive case finding (PCF) to detect people with tuberculosis (TB). PCF is defined as detecting TB at health facilities among persons who seek medical care on their own.
