RmYN02 is a bat-derived strain of Severe acute respiratory syndrome–related coronavirus.

It was discovered in bat droppings collected between May and October 2019 from sites in Mengla County, Yunnan Province, China.

All genetic data were found by Weifeng Shi and his team.

[1] RmYN02 was collected between May and July, 2019, in Yunnan by Professor Alice C. Hughes from Xishuangbanna Tropical Botanical Garden, and sequenced by Weifeng Shi from Shandong Medical University, based on an analysis of 302 feces samples collected from 227 bats that were collected from Mengla County, Yunnan Province, China, within a short distance from the Xishuangbanna Tropical Botanical Garden.
