Follow-up of the staff routinely exposed includes:
– Clinical examination once per year;
– Assessment of TB and HIV for any symptomatic staff;
– Chest X-rays if clinical signs are observed (not routinely).
Staff presenting with a recent risk of an immunocompromised state (HIV infection, immuno-suppressive treatment, etc.) and newly pregnant women should not remain exposed. According to the context and the level of risk, they should be transferred to another department or to the least TB-exposed position (Section 14.2.3).
Long-term (at least 36 months) isoniazid preventive therapy is recommended for all HIV-infected health staff known to be TST-positive, including those who convert from TST-negative to TST-positive (see Chapter 16 for more information).
