ABSTRACT
The risk assessment for health professionals inherent to aerosols inhalation, although significant (Singh, 2009), is difficult to relate by the few data available on the real workers exposure. A real knowledge about this reality is only possible by measuring the exposure and knowing dose-response relationships (Schlosser et al., 2008), whose is scarce (Gehanno et al., 2009). Traditionally the prevention and control of aerosols exposure have three levels of intervention: the elimination of the source or, when that is not possible, it should be necessary to monitor and control the exposure and the source (Xu et al., 2011). Therefore and to minimize the presence of bioaerosols it is recommended to implement the following measures: humidity control, equipment maintenance, promotion of natural ventilation, placement of exhaust air filters (HEPA), use of disinfectants to decontaminate the air and surfaces (Vaquero et al., 2003; Srikanth et al., 2008), keep the
1 INTRODUCTION
Biological agents are important sources of infection transmission in the hospital settings (Rezayee et al., 2011). They represent a significant role in the definition of indoor air quality (Camacho, 2010) with implications in different areas.
