Brief Summary:

Highly communicable and virulent diseases, the ongoing threat of emerging infectious diseases, and the prospect of bio-terrorism have become part of the new reality for health care workers. SARS transmission has occurred despite the use of droplet, contact, and airborne precautions. Potential explanations for some of the episodes of "through-precautions" transmission include the possibility of contamination during removal of protective clothing.

The recommended protective systems (PPS) for aerosol generating procedures set out by the US Center for Disease Control and Prevention (CDC) and the Ontario Ministry of Health and Long Term Care (MOHLTC) differ.

The failure of a PPS may be associated with significant consequences in terms of the morbidity and mortality of front-line health care workers. The purpose of this study is to determine if a difference exists between the rate of self-contamination due to deficiencies in contact precautions for individuals wearing either the CDC or MOHLTC recommended PPS.

Study participants will don one of the two recommended PPS, be "contaminated" with an indicator that becomes visible under ultraviolet light, and then assessed for contamination of clothing layers and skin after removal of the PPS. They will then repeat the procedure using the other PPS.
