The virus is found in South and Southeast Asia, China, Japan, and Taiwan.^[4] From 1970 to 1977, RGSV incidence was high in Indonesia. Outbreaks occurred in the Philippines from 1973 to 1977 and again from 1982 to 1983.^[5] There was significant crop loss from RGSV in parts of India in 1972–74, 1978, 1981, and 1984.^[6][7] High levels of RGSV were reported in Kyushu, Japan in 1978.^[8]

From 2000 to 2008, the Mekong Delta of Vietnam experienced major crop losses of rice as RGSV and rice ragged stunt virus, also vectored by N. lugens, occurred together.^{[9][10][11][12]}
