Which population has an increased risk of contracting tuberculosis?

Healthcare workers have an increased risk of contracting tuberculosis (TB) due to their potential exposure to infected patients. Tuberculosis is primarily transmitted through airborne droplets, and individuals in healthcare settings, such as hospitals or clinics, often interact closely with patients who may have active TB. Because healthcare workers are in environments where TB transmission can occur, they are considered at higher risk and are often provided with specific training and protective measures to mitigate this risk.

In contrast, while patients with diabetes are known to have a higher susceptibility to infections in general due to compromised immune function, their risk specifically for contracting TB primarily depends on other factors such as exposure history rather than diabetes itself being a direct cause. Individuals living in rural areas may have variable exposure risks, and while some may be at risk for TB, it is not inherently tied to their living situation. Regular exercise does not correlate with an increased risk for TB; in fact, maintaining good physical health can support overall immune function. This contextual understanding highlights the unique vulnerability of healthcare workers in relation to tuberculosis exposure.
