Title Regulating the risk of tuberculosis transmission among health care workers
Bibliographic information May-June 2000, Vol.61, No.3, p.334-339. Illus. 20 ref.
Abstract The relationship between tuberculosis (TB) infection and disease rates is discussed, and a probability framework is introduced for the apportioning of the infection risk between occupational and non-occupational exposure. It is argued that most TB infections among health care workers are work-related. A 0.2% overall annual risk of TB infection is proposed as acceptable, because in the context of an infection surveillance programme it limits the cumulative disease risk faced by health care workers close to the value for the general United States population. Based on the probability framework, an estimate of the background community infection rate and the traditional Wells-Riley risk model it is shown that a target workplace infection risk value can be derived and applied to risk management decision making.
