Overview

Cohort study determines high prevalence and conversion rates of tuberculosis infection in healthcare workers, indicating strong need for improved diagnostics.

Key Points

  • This study aims to assess the prevalence and conversion rates of Mycobacterium tuberculosis infection among healthcare workers in a TB treatment hospital.
  • Conducted a prospective cohort study with 178 healthcare workers at UANL from 2017 to 2019.
  • Participants were tested at baseline using QuantiFERON-TB Gold Plus and Tuberculin Skin Test.
  • Those testing negative were retested 4-18 months later to check for conversion to infection.
  • Baseline prevalence of tuberculosis infection was found to be 63.5%.
  • Males, nurses, and administrative staff exhibited higher odds of infection.
  • Approximately 30.8% of negative baseline participants converted to infection at follow-up.
  • There was fair agreement between the QuantiFERON and Tuberculin Skin Test results.
