Almost eery fig has FMV. Some are clean, but they will catch the virus if they are sent to you. This is nothing to worry about. Makes the leaves a little blotchy, but does not KILL the tree. And when a tree get's old, the virus moves on to younger trees. Almost all my trees have it, but they bear delicious fruit. Maybe you should welcome it. The tree thinks it's dying, so it's fruit is the best!!
Certain climates struggle with the virus, so here in Sunny Southern California, it's not a problem, but in cold places, might be too much for a tree to bear.
