||The containment efficiency of patient isolation enclosures in hospitals must be verified to protect staff, other patients and visitors. This article reports on the development and validation of a simple technique to measure the low count concentrations of escaping airborne particles that might be present outside an isolation enclosure, based on micrometer-sized fluorescent polystyrene latex microspheres as a surrogate for pathogenic bioaerosols. Particles are released into the isolation enclosure and air is sampled inside and outside the room to capture airborne particles on 25mm diameter filters, which then allows the number of particles to be quantified using a random field counting approach. The method was found to be specific, sensitive and accurate.
