Title Refining a risk model for occupational tuberculosis transmission
Bibliographic information Jan. 1996, Vol.57, No.1, p.16-22. Illus. 18 ref.
Abstract A probability model is presented to describe the variation with time of levels of exposure to Mycobacterium tuberculosis aerosol experienced by health care workers. Based on this model, analytical solutions are presented for an individual worker's cumulative risk of tuberculosis infection, and for the worker population mean cumulative risk of infection, with and without use of respiratory protection. Given exposure estimates and a definition of acceptable risk, the risk equations developed in this analysis may be used to assist in the selection of respiratory protection for health care workers.
