A very recent,( February 17, 2015) European Journal of Plant Pathology scientific, reviewed paper reported that in Palampur, India:
"32 different samples of wild roses were collected from the floriculture division (CSIR-IHBT), where the institute maintains a germplasm of domesticated wild roses. The samples were tested by Double antibody sandwich-Enzyme linked immunosorbent assay (DAS–ELISA) and dot-blot hybridization and the results were validated by RT-PCR which confirmed the presence of CNRMV in 34 % of the tested samples, belonging to the species: R. brunonii, R. multiflora, R. cathayensis and R. alba."
They bring up the possibility that the virus could be spread by aphids. The article shows pictures of infected leaves, but points out that not all infected leaves tested positive for the virus.
The title of the paper is: "Wild roses as natural reservoirs of Cherry necrotic rusty mottle virus"

The following is a 2012 PDF download report from U. California, Davis which reports finding low numbers of CNRNV infections in their Prunus species collection (Cherry 4%, peach 3.2%, and plum 2.5%). Unfortunately, they do not know the countries of origin of their infected plants.

This virus has been reported to infect sweet cherry trees: "CNRMV infects sweet cherry (Prunus avium) and has been reported in North America, Europe and Japan [3, 7, 13, 16, 19]."
