In a recent study, scientists have uncovered 20 new viruses in bats from Yunnan province in China. This research has raised alarms about the potential health risks these viruses could pose to humans.
The study, published in the journal PLOS Pathogens, involved analyzing kidney tissue from 142 bats collected between 2017 and 2021. Among these viruses, two new henipaviruses were found that are genetically similar to the deadly Hendra and Nipah viruses, which have caused serious outbreaks in both people and animals in the past.
Professor Vinod Balasubramaniam, a molecular virologist from Monash University in Australia, highlighted the importance of these findings, stating, “These viruses are particularly concerning because they were predominantly found in bat kidneys.” This is worrying as the kidneys help produce urine, which can contaminate fruits or water, posing a risk of infection to anyone who consumes these items.
The newly identified viruses, named Yunnan bat henipavirus 1 and 2, share about 52% to 57% of their genetic material with the notorious Hendra and Nipah viruses. These viruses have previously led to severe brain infections and high fatality rates among those affected.
Bats are known carriers of many viruses that can infect humans, including those responsible for diseases like Ebola, SARS, MERS, and even COVID-19. Experts believe that these viruses can jump from bats to humans or other animals, often through contaminated food or water. The importance of studying bats is underscored by the fact that their unique biology allows them to carry a wide range of unknown microorganisms.
In addition to the new viruses, researchers also discovered a new single-celled parasite named Klossiella yunnanensis and two bacterial species, one of which had never been described before and is now called Flavobacterium yunnanensis.
The findings from this study show the need for more research into the various microorganisms present in bats. Understanding what types of viruses and other pathogens live in bat organs, particularly their kidneys, is crucial for public health.
The Yunnan region has a climate similar to places that have seen Nipah virus outbreaks before, such as Malaysia, making it essential to monitor wildlife in this area closely. Scientists emphasize that further studies are needed to keep an eye on the spread of new viruses in animals, potentially preventing future outbreaks before they reach humans.
