HCWs should ensure they minimize the time spent with such patients in areas that are overcrowded or poorly ventilated. Although the interferon-gamma release assay has some advantages over the tuberculin skin test, the former has serious limitations, mostly due to its high conversion rate. Centers for Disease Control and Prevention 1. Achieving this goal is nearly impossible if we do not prioritize implementing and scaling new, effective interventions to accelerate the case decline from percent per year to percent per year.

The only exception to this is, as described above, when someone has infectious XDR TB, and it is not feasible to isolate them at home. If such physical barriers are not available, the best practice is for the mouth and nose to be covered with the bend of the elbow or the hands, which must then be cleaned immediately.
Three strategies should be leveraged to achieve those goals. Ensuring the availability of recommended laboratory processing, testing, and reporting of results 5. Often, this value does not get the recognition it deserves.

Abstract It is well established that health care workers HCWs have a considerably higher risk of occupationally acquired tuberculosis TB. Although there is no sure-fire way to completely prevent the spread of TB at this point in time, there are a number of measures that can be put in place to reduce the spread of the illness. Implementing effective work practices for managing those who may have TB disease 6.

Recently, the United Nations issued a political declaration at the High-Level Meeting on Tuberculosis TB to rally an urgent global response to a global epidemic. There is more about respirators and masks. But some people who have latent TB infection are more likely to develop TB disease than others.
