It depends on the microbe.
HIV, while quite deadly, is actually an extremely fragile virus. It can only survive in the human body. Exposed it to air, for a short period, and it's toast (let alone anything else).
Now if we are talking about blood samples, that's a little different. HIV in a large enough blood sample, outside the body, is like an astronaut in a capsule...eventually they'll run out of air...
Even on a toilet seat, it's a goner. There are too many factors, but on the whole, your 99.9% safe.
I'd be more worried about a variety of other nasty bacterium that can infect you.
