Occupational Risk of Airborne Exposure: A Situational Analysis in a Three-Tier Public Healthcare System in South Africa.

This study aimed to detect airborne (MTB) at nine public health facilities in three provinces of South Africa and determine possible risk factors that may contribute to airborne transmission. Personal samples ( = 264) and stationary samples ( = 327) were collected from perceived high-risk areas in district, primary health clinics (PHCs) and TB facilities. Quantitative real-time (RT) polymerase chain reaction (PCR) was used for TB analysis.
