May want to check out this ref in Lancet:
http://pdf.thelancet.com/pdfdownload?uid=llan.361.9368.original_research.25515.1&x=x.pdf Its a retospective study of SARS infected Hong Kong healthcare workers-looked at what protective gear they wore, and determined what measures were most likely to protect against infection.
Turns out that simple surgical mask and gowning ( N 95 mask not necessary) was probably sufficient protection.
This is valuable info going forward as we look for sensible and economical means to deal with suspect cases.

I take exception to your post that N95 masks aren't necessary. Otherwise, thank you for posting...
