The Global Impact of Tuberculosis

Slide 2

November 2009

When discussing any topic related to tuberculosis, I think it’s always important to begin by underscoring the significant global impact of this disease. In 2007, the Centers for Disease Control and Prevention estimated that nearly 2 billion persons, or 1/3 of the world’s population, were infected with TB. Among those that are infected worldwide, approximately 9 million develop active TB disease and roughly 2 million die from TB each year. This disease is especially problematic in the HIV population, with recent data suggesting that 1/3 of HIV-infected patients are coinfected with TB, and that nearly 50% of deaths among HIV infected persons are attributed to TB. These figures are really quite staggering, and highlight why new and improved diagnostic methods are desperately needed to identify those with active and latent tuberculosis infection.
