Chinese Scientists Discover 22 New Viruses in Bats, Raising Global Health Concerns
Yunnan, China – Researchers in China have identified 22 new viruses in the kidney tissues of 142 bats. The study, conducted in Yunnan province from 2017 to 2021, used advanced genetic sequencing. Two of the viruses are closely related to the deadly Hendra and Nipah henipaviruses. These pathogens can cause severe brain inflammation and respiratory illness in humans, with mortality rates up to 75%.
The bats, primarily fruit-eating species, were captured near village orchards. Scientists warn that bat urine could spread these viruses to humans through contaminated fruit or water. Past outbreaks, like Nipah in Bangladesh, show this risk is real. The viruses share 52-57% genetic material with Hendra and Nipah, raising fears of potential spillover to humans or livestock.
“This discovery highlights the diversity of bat viruses,” said Linfa Wang, a professor at Duke-NUS Medical School. “It’s concerning because these bats live close to human settlements.” The study, published in PLOS Pathogens, calls for urgent surveillance to prevent outbreaks.
Experts note that while the viruses are alarming, further research is needed. “We don’t yet know if they can infect humans,” said Alison Peel, a wildlife disease ecologist at the University of Sydney. Laboratory studies will determine the actual risk.
Yunnan’s climate is similar to regions hit by Nipah outbreaks, like Malaysia. This makes it a critical area for monitoring zoonotic diseases. The World Health Organization lists Nipah as a priority pathogen for pandemic preparedness.
The findings underscore the need for global vigilance. Bats are known carriers of dangerous viruses, including SARS and Ebola. Researchers urge stronger biosecurity measures to protect humans and animals.
