| Abstract |
Even workers wearing respirators may be infected following inhalation of respirable particles, termed droplet nuclei, that carry viable mycobacterium tuberculosis bacilli. Based on the expected number of infectious doses inhaled, the Poisson probability model is used traditionally to predict an individual's risk of infection. This article synthesizes the beta distribution, as applied to average penetration values among a respirator-wearing population, and the Poisson distribution, as applied to an individual's infection risk, to describe the population risk of Mycobacterium tuberculosis infection. |
