Block 5: TB and occupation in South Africa - Potential Interventions To Reduce TB Incidence In Silica Exposed Workers

POTENTIAL INTERVENTIONS TO REDUCE TB INCIDENCE IN SILICA EXPOSED WORKERS.

The figure illustrates the potential interventions to reduce TB incidence in silica exposed workers. For a more detailed discussion of these interventions consult:

TB TREATMENT AT THE WORKPLACE:

TB treatment is a highly cost effective health intervention that both saves lives and prevents disability. Workplace treatment further ensures that workers with TB do not suffer economic losses as well.

The high burden of TB in South Africa means that TB treatment and control is an issue for every workplace, not just those workplaces where there is increased risk of TB due to silica exposure.

In most instances TB drugs are supplied by local authorities, either directly to the workplace or via the worker once he has been diagnosed. The workplace clinic must then make arrangements for Directly Observed Therapy (DOTS).
