According to the Canadian Health Dept it can survive for days dried up on a table. Takes 5 minutes of boiling to kill it. Disinfectants do also work. A few as 1 organism can result in an infection.

You beat me to it!
It also says ultra violet radiation kills it. Instantly. It would have to be a ton of live virus in liquid to live for that long. Dried is simply not proven to cause infection. Even if spores were still alive in dried form out somewhere in the public (always in the dark mind you) whoever came in contact with it would STILL need to absorb it into their blood stream. It’s infectious not contagious.
What I discern from all of this is that Africa is filthy place and the people there live in filth and do nothing about it.
