Twenty new bat viruses, including two closely related to the deadly nipah and hendra variants, have been discovered in China.
In the new study, researchers looked inside the kidneys of 142 bats from ten species, collected over four years across five areas of Yunnan province.
Using advanced genetic sequencing, the team found 22 viruses – 20 of them never seen before.
Two of the most concerning were new henipaviruses, the same genus as nipah and hendra viruses, which are known for their high fatality rates in humans.
The henipaviruses were found in fruit bats living near orchards close to human villages.
Since henipaviruses can spread through urine, and the viruses were found in the bats' kidneys, the study raises concerns about contaminated fruit and the risk of these viruses jumping to humans or livestock.
University of Sydney wildlife disease ecologist and veterinarian Dr Alison Peel said while the discovery was "concerning", it was not yet known if the new viruses could infect humans.
"We have other examples of close evolutionary cousins to hendra and nipah that appear not to be of any concern for spillover, so there will need to be some more laboratory studies on these new viruses to determine the actual risk," she said.
Peel said the link between virus-carrying bats and fruit orchards in China provided a lesson to Australia.
