I am thinking the “tube system” refers to a vacuum transport tube system (like the drive up teller at the bank or the one for cash at Costco)...take a blood sample, seal the vial, label it, put it in a “carrier” and send to the hospital lab for testing.
Yeah, that could be.
At least Ebola virons wouldn’t stay viable for very long in that kind of tube system — would dry out very quickly. The first few canisters you put through it though could possibly end up contaminated.

Yikes! Where does the exhaust air go? Is it filtered (on the way out)?
