Kinetics are presented where known, with summary schematics for reaction mechanisms. 1. 'All Intensive Purposes' or 'All Intents and Purposes'? It may seem intuitively obvious that the virus would thrive in fabrics and other porous materials and do poorly on non-porous surfaces like steel and glass, but the CSIRO group found just the opposite. At 86 o F the group was able to recover infections virus from steel and glass for 7 days, but only 3 days for cotton cloth and vinyl.
