news.A study has shown that when Quigley Pharma's QR-441 compound is sprayed onto the air filters of respiratory masks, the devises offer greater protection against avian flu and the human influenza virus H3N2 than the air filters alone.

The QR-441 impregnated masks prevented up to 99% of the viruses whereas the masks not treated with the compound only had the ability to prevent up to 90% of the viruses passing through. The compound also worked to deactivate the live viruses passing through these filters.
“If there is an outbreak of avian flu in our US human population, initially it will be easier to distribute the formula as a spray to be used on the exterior of commercially available masks than to develop and distribute a new style mask using the compound. In an emergency situation, the spray formula’s increased ability to stop the virus from penetrating these masks may help reduce viral transmission,” said Charles Phillips, senior vice president at Quigley.
The company said it is pursuing several development plans with all relevant government agencies and private organizations for various levels of approval. Products would be aimed at protecting people at high risk of avian flu and for use in emergency medical situations.
