    Follow-up of routinely exposed staff includes:

    • An annual clinical evaluation.
    • Assessment for TB (including CXR) and HIV, if symptomatic.


    For staff who were TST or IGRA negative at baseline, TST may be performed once a year.


    Staff working in a TB department and presenting with a recent immunodepression (e.g. HIV infection, immunosuppressive treatment) or a pregnancy, should be transferred to another department or to an area within the TB department where the risk of exposure to M. tuberculosis is low (Chapter 14).


    LTBI treatment (Chapter 16) should be offered, after exclusion of active TB:

    • Once to staff who become TST or IGRA-positive.
    • To all HIV-infected staff.
