Screening for TB by spot sputum culture is possible and a promising alternative to mobile X-ray in a community based screening programme. 22.2% did not have chest X-ray suggestive of TB and would not have been identified using mobile X-ray. Most of the TB cases were smear-negative, suggesting that they were identified at an early, less infectious stage, which is essential in order to prevent transmission and gain infection control.
These findings suggest that ACF reduces morbidity and infectiousness among TB patients, thereby potentially improving health outcomes and reducing transmission of M. tuberculosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
