Inadequate hospital ventilation system increases the risk of nosocomial Mycobacterium tuberculosis.

The ambient air in nine locations in a pulmonary hospital and a tuberculosis diagnostic laboratory was analysed to determine the hazard posed by Mycobacterium tuberculosis. In four locations, between 6 and 20 M. tuberculosis cell equivalents/m(3) were detected. The results indicated that inadequately ventilated corridors had the highest cell equivalents. In these areas healthcare workers were less aware of infection hazard compared to areas with known sources of M. tuberculosis and the wearing of protective masks and passive ventilation were not in place. Based on these results, further infection prevention and control measures need to be implemented. Copyright © 2011 The Healthcare Infection Society. Published by Elsevier Ltd. All rights reserved.
