Abstract
The invention discloses a method of preventing transmission of viral pathogens between a source of viral pathogens and a target of said viral pathogens comprising positioning between said source and said target a microporous membrane material comprising (1) a thermoplastic polymer or polytetrafluoroethylene and (2) a water- and oil-repellent fluorochemical compound which provides said membrane with oleophobic, hydrophobic and viral barrier properties.
