In a prison setting, systematic screening using CAD4TB and portable X-ray systems screened over 20,000 inmates, identifying a TB prevalence 1.8 times higher than the national average. Discover how this approach underscores the importance of regular TB screening in prisons, utilizing technology to facilitate mass screening and reduce transmission.

  • Systematic screening in prison setting using CAD4TB with portable X-ray system.
  • 20,557 inmates were screened and 1,964 (10%) were identified as presumptive TB cases with a CAD4TB score ≥70 and/or as being symptomatic.
  • TB prevalence at prisons is around 1.8 times higher than the estimated national prevalence.
  • TB screening is necessary at prisons as part of routine practice and use of technology enables mass screening and higher yields of MTB cases, reducing transmission.
