@GigiPlumeria I am not a botanist or scientist of any sort so these are just my observations. You are correct in your observations of seeing MV in plants for sale online. I have stopped buying plants that I can't touch first after I received plants that were infected and the vendor wouldn't compensate. If you have a trusted vendor you're safer. Isolate all new plants until you see new leaves and new flowers. I do have some infected plants and it is a real pain to have to have to be so careful with disinfecting tools etc. I have been experimenting with seed propagation of infected plants but it's at least a two/three year project so I have no answer yet. I have been using insecticides on my test group (I don't normally use chemicals) to try to keep the insect vectors from spreading to other plants. Also my home is on four city lots so I can keep them separated. If you don't have room to do that you're better off/safer to destroy the infected plants.
Mosaic Virus, specifically Cucumber Mosaic Virus, was first confirmed in Adeniums in 2012. It has run rampant through some Taiwanese growers due to sloppy grafting practices. Cucumber Mosaic Virus can be transmitted through seeds but I have not seen evidence in my seedlings that are six months to a year old so it's possible that the virus infecting my plants is not transmitted through the seeds. Fingers crossed!
