Miners are at an increased risk of developing tuberculosis (TB) due to their occupational exposure in enclosed and poorly ventilated spaces, which can facilitate the transmission of airborne pathogens. Mining environments often require long hours spent underground in tight quarters, where the risk of exposure to infectious agents is heightened. In addition, individuals in such settings may experience compromised respiratory health from dust exposure and other occupational hazards, potentially lowering their immune defenses against infections such as TB.

In contrast, while farmers, teachers, and construction workers may face health challenges from their environments, their risk for TB is not typically elevated to the same extent as that of miners. Farmers may encounter zoonotic diseases depending on their livestock exposure, teachers primarily engage with healthy populations in an open environment, and construction workers might face injuries and other physical risks, but these occupations do not involve the same close contact and confined settings inherent to mining work, where TB transmission is more likely to occur.
