In a recent breakthrough, scientists found two new henipaviruses in bat kidneys in China’s Yunnan province that resemble the deadly Nipah and Hendra viruses, capable of causing severe illnesses in humans. This discovery highlights the potential zoonotic threats and the importance of global vigilance for emerging diseases post-COVID.
Why in News?
A team of researchers studying bats in Yunnan province discovered two new viruses closely related to Nipah and Hendra viruses, raising concerns about potential zoonotic transmission and future outbreaks. The study underscores the importance of monitoring diseases originating from wildlife, especially after the COVID-19 pandemic.
Background & Discovery
- Kidney samples from 142 bats
- Collected over 4 years (2017–2021)
- Located in Yunnan province, China
- Researchers identified 22 different viruses, including Yunnan bat henipavirus 1 and 2.
Key Findings
- Genetic similarities with Nipah and Hendra viruses
- Found in bat kidneys associated with urine production
- Potential indirect transmission to humans through contaminated fruits or water
- May cause encephalitis and severe respiratory symptoms
- First complete genomes of such henipaviruses in Chinese bats
Expert Opinions
- Professor Vinod Balasubramaniam, molecular virologist, expressed concerns about potential human exposure through contaminated food or water.
Significance
- Emphasizes the importance of early detection to prevent future pandemics
- Highlights the need for global pathogen surveillance, zoonotic disease monitoring, and public health preparedness
- Reinforces the interconnectedness of wildlife, agriculture, and human health
