A Quick TB Primer
From the excellent student blog, Now @ NEJM:
In 2011, there were 8.7 million new cases of active tuberculosis worldwide. Recent advances in diagnostics, drugs, and vaccines and enhanced implementation of interventions are helping to improve the prospects for global tuberculosis control. The latest review in our Current Concepts series covers the diagnosis and treatment of latent, active, and drug-resistant tuberculosis and also reviews new drugs and vaccines.
Despite the availability of a cheap and effective cure, tuberculosis remains responsible for millions of active tuberculosis cases and deaths worldwide, disproportionately affecting the poorest in both high-income and developing countries. Recent advances in new diagnostics, drugs, and vaccines and enhanced implementation of existing interventions now provide optimism for improved clinical care and prospects for global tuberculosis control.
