UCD (University of California /Davis) they have a fig propagation program, they distribute cuttings of named varieties and for the most part are infected.

I believe that virused plants should not be distributed. Most of the Brooklyn Botanic Garden figs are virused. I noticed green leaves there with a similar discoloration as your Dendrobium, but then those signs disappear when the weather gets warmer and new growth takes off. I wonder if in Orchids the mosaic virus may be present and asymptomatic and only show up when the plant is stressed by other co factors
