What Factors Affect TB Transmission?

Businesses with a large migrant workforce, such as oil and gas companies, mining companies as well as health centres/hospitals, are workplace settings where there is an increased risk of TB. Transmission generally occurs indoors, where droplets can stay in the air for a long time due to poor ventilation.

TB is also more easily spread in crowded living, working or social conditions, such as in hostels, prisons, military barracks and shebeens.
