Does a virus survive vacuum?

[leo hansen]

Did any one else see the article in the March issue of Chemcial 
Engineering Progress that described high pressure, i.e., > 10,000 Atm, to 
process food.  Some Japanese companies have developed processes using 
these pressures to sterilize food products by forcing chemical 
modifications to the bacteria.  I don't remember if viruses were also 
affected, but I don't see why not.  Rather than vacuum maybe high 
pressure will render virus harmless, note I didn't say kill.
