If a tree or other plant has a viral infection then it can not spread to humans because the virus can only reproduce in the living cells of the tree or plant.
Why would you want to add a virus to a tree?
Are people going to eat the fruit/seeds/leaves of the tree?
There is evidence that plant viruses can infect humans, but there are no known plant viruses that are clinically shown to be human pathogens.

So, for example, if you're writing a sci-fi story it is a plausible plot device.
H2O is water

Say if, i added some type virus in a tree will it come out with the h20 and people will catch it?
