Conclusion: Influenza can be ruled in but not ruled out through the use of RIDTs. Sensitivity varies across populations, but it is higher in children than in adults and for influenza A than for influenza B.

Lab study supports use of N95 respirators for flu protection

Robert Roos * News Editor

Apr 3, 2012 (CIDRAP News) – “A new laboratory study supports the long-debated view that airborne viruses play a role in spreading influenza and that N95 respirators provide the best protection against airborne viruses, with surgical masks affording much less.

A US-Chinese team of researchers created a simulated examination room with mechanized mannequins spaced 6 feet apart to represent coughing and breathing humans. They found that flu viruses floated between the two and were “inhaled” by the breathing mannequin, but that an N95 respirator sealed to the mannequin’s face stopped 99.8% of them.

A poorly fitted respirator or a loose-fitting surgical mask, by contrast, blocked only about two thirds of the virus particles….”

Conclusions. These results support a role for aerosol transmission and represent the first reported laboratory study of the efficacy of masks and respirators in blocking inhalation of influenza in aerosols. The results indicate that a poorly fitted respirator performs no better than a loosely fitting mask.
