oa South African Family Practice - Letter : protective role of vitamin D as a cellular immuno-modulator in tuberculosis infected health care workers : correspondence

 

Abstract

I would like to raise a concern about health care workers' (HCW) exposure to tuberculosis. Tuberculosis (TB) is a significant occupational problem among HCW in low- and middle-income countries. The greatest single risk factor for developing TB from infection is concurrent HIV infection. In the period from 1994 to 2006, TB incidence increased 4.2 times in South Africa (SA) while it was halved in the United States of America (USA). The risk ratio, based on the ratio of the incidence of TB, is over 300 times higher for HCW in SA than in the USA in 2006 (1 133 vs 3.7 per 100 000).
