The latent tuberculosis infection survey using two interferon γ release assay tests among the elderly in a well-confined rural county in Eastern China.

ABSTRACT:

Background

Tuberculosis (TB) latent infection is a crucial precursor to the development of active pulmonary tuberculosis while currently no gold standard for detecting latent infection. This study aims to investigate the prevalence of latent infection among the elderly in high-incidence areas in Eastern China. Additionally, it compares the agreement of two interferon-γ release assay (IGRA) reagents in detecting latent TB infection in this elderly population.

Methods

A random sampling method was adopted to select two townships from Lanxi City, China. Based on the health check-ups for the elderly under the National Basic Public Health Service Project, a questionnaire survey and latent infection testing were conducted among the recruited elderly population aged 65 and above.
