Occupational tuberculosis (TB) risk has increased, particularly for healthcare workers exposed to high-risk populations. This study quantifies this risk and identifies barriers to worker protection, offering recommendations to mitigate TB transmission in the workplace.

Area of Science:

  • Public Health
  • Occupational Medicine
  • Infectious Disease Epidemiology

Background:

  • Tuberculosis (TB) incidence has risen, especially in vulnerable populations and among healthcare workers.
  • Increased occupational risk for TB is linked to exposure to high-risk individuals in healthcare and correctional settings.
  • The precise magnitude of occupational TB risk remains unclear, necessitating further investigation.

Purpose of the Study:

  • To determine the extent of occupational risk for tuberculosis acquisition.
  • To identify factors contributing to increased TB risk in the workplace.
  • To propose strategies for reducing occupationally acquired TB.

Main Methods:

  • Analysis of databases with occupational exposure information.

  • Telephone surveys to assess worker exposure and risk.
  • Review of employee conversion rates at high-risk institutions.
  • Documentation of TB infection and disease rates over time.

    • Main Results:

    • High employee conversion rates were observed following accidental exposures.
    • Changing rates of TB infection and disease were identified.
    • A relative scarcity of reported TB disease and deaths among workers was noted.
    • Numerous barriers to effective worker protection against TB were identified.

    Conclusions:

    • Occupational TB poses a significant, though not fully quantified, risk to healthcare and other frontline workers.
    • Accidental exposures can lead to high rates of TB transmission.
    • Barriers to worker protection must be addressed to reduce the incidence of occupationally acquired TB.
