Abstract: |
Occupational TB has been an emerging infectious disease among healthcare workers. Its incidence spiked in the late-1980s and early 1990s, when nosocomial outbreaks of TB, including MDR-TB, caused alarm. Its incidence has clearly dropped since the mid-1990s, a trend largely due to intensified (or, in some cases, brand new) infection control practices. Despite the consistent decline in nationwide TB case rates, the issue of occupational TB remains important and deserving of further study. Complacency on the part of hospitals and policymakers has been widely implicated in the dramatic resurgence of TB in the mid-1980s, when HIV and demographic changes led to a rise in cases. As the incidence of TB among healthcare workers declined from the 1950s to 1980, there was a slackening of infection control measures, "if not outright nelgect of such practices". It is very likely that there will be another resurgence of TB if the vigilance adopted in the past 10 years is relaxed. |
