Roughly one-quarter of the world's population has been infected with M. tuberculosis, [6] with new infections occurring in about 1% of the population each year.

The main risk is that approximately 10% of these people (5% in the first two years after infection and 0.1% per year thereafter) will go on to develop active tuberculosis.
