(ii) Does it identify more at-risk contacts? (iii) Does it result in more TB cases being prevented?Home and work visit allowed to identify more at risk contacts (8.4/index case) than the interview (2.5/index case); to improve compliance (87.3% of the identified contacts were screened, compared to 67.6%). More cases of active TB and LTBI cases were detected (1.4/index case compared with 0.75/index case) and prevented more TB cases in the future.The newly implemented contact-screening program with home and work place evaluation of active TB patients, improved compliance to screening procedures, identified more at-risk contacts and should allow us to prevent more TB cases in the future. %U
