BEIJING: Scientists in China have raised alarms over the discovery of 22 new viruses found in bats, warning that these pathogens could pose a greater threat than COVID-19. A recent study reports that these viruses, uncovered in bat samples collected from Yunnan province between 2017 and 2021, present a serious global health risk. The viruses were detected in the bats' kidney cells, with two strains found to be genetically similar to the deadly Nipah and Hendra viruses.

The research highlights growing concerns over the impact of environmental changes such as climate change, deforestation, and rapid urban expansion. These factors are bringing humans and wildlife into closer contact, increasing the risk of zoonotic spillover—where viruses jump from animals to humans—as seen with past outbreaks like SARS, Ebola, and COVID-19.

The study also found that two of the new viruses were present in fruit bats living near agricultural areas. This raises the possibility of virus transmission through contaminated fruits, as bat urine may taint produce in orchards and gardens. Since bats typically do not leave bite marks on fruits, humans might unknowingly consume infected produce, potentially triggering outbreaks.

If transmitted to humans, these viruses could cause severe respiratory issues and brain inflammation (encephalitis), researchers warned. The estimated fatality rate is as high as 75%. Despite the grave potential, there have been no recorded infections in humans or animals so far.
