the emerging gold standard for ltbi, page-4

The national bodies entrusted with controlling and eradicating TB are being criticised for their failure.
TB in some form is present in 2B people. Most in the developing world, but there is an increasing rate of infection in the developed world.
The national bodies are being blamed for this.
Thec reason it seems to me is that there are not gfiving enough attention to detecting Latent TB.
So I expect an bigger effort being put into this area.
CST is well placed to benefit from this.
