ClinConnect Summary

Latent TB infection, hereafter referred to as TB infection, continues to be a significant driver of the global TB burden. A recent re-estimation using mathematical modeling demonstrated that to end TB by 2050, at least one-quarter of the global population living with TB infection would require TB preventive therapy (TPT).

The Tuberculin Skin Test (TST) and Interferon-Gamma Release Assays (IGRA) are the two preferred diagnostic methods for detecting TB infection. TST utilizes Tuberculin PPD RT 23 intradermally, which is low-cost and can easily be performed in the field. TST is currently the...
