Abstract

This report demonstrates that using interferon gamma release assays to screen for latent tuberculosis infection in female commercial sex workers in an outreach sexual health clinic is feasible and acceptable. Routine interferon gamma release assay use successfully identified high numbers of latent tuberculosis infection. Innovative approaches to treatment and follow up were required to improve treatment adherence in this group. Direct observation of therapy within the sexual health clinic was also feasible. Successful follow up was dependent on the support of outreach workers, interpreters and tuberculosis nurses.
