If the price comes from Andromeda Strain protection levels, then that needed to be stated explicitly. Also, one would think that price hike would be most noticeable in Biology related labs, not all equally.

Strangely most fiction I've see in which characters get infected, they are horribly blase about even basic precautions. Star Trek away teams almost never wore suits and touched everything with bare hands.
