A METHOD FOR PREVENTING TRANSMISSION OF VIRAL PATHOGENS

摘要

The invention discloses a method of preventing transmission of viral pathoge ns between a source of viral pathogens and a target of said viral pathogens comprising positioning between said source an d said target a microporous membrane material com- prising: 1) a thermoplastic polymer or polytetrafluoroethylene and 2) a wate r- and oil-repellent fluorochemical compound which provides said membrane with oloephobic, hydrophobic and viral barrier properties, said membrane being oriented in at least one direction.
