- Scientists in China have identified HKU5-CoV-2, a bat coronavirus capable of binding to human ACE2 receptors.
- The virus is genetically linked to MERS-CoV, raising concerns about its zoonotic transmission potential.
- Researchers stress the need for global surveillance and biosecurity measures to prevent future outbreaks.
The discovery of HKU5-CoV-2, a bat coronavirus strain found in China, has raised alarms due to its ability to bind to human ACE2 receptors. This suggests a potential risk of human infection, similar to SARS-CoV-2, the virus responsible for COVID-19.
Scientists emphasize the importance of proactive monitoring and research to understand how bat coronaviruses adapt to human hosts.
Scientists Warn of Emerging Bat Coronavirus with Pandemic Potential
HKU5-CoV-2 belongs to the merbecovirus subgenus, which includes MERS-CoV, a virus that caused a deadly outbreak in 2012. Its genetic similarities suggest a possible high-risk scenario where the virus could jump from bats to humans through an intermediate host, evolving further in the process.
The ability of HKU5-CoV-2 to infect human cell cultures and mini-organ models indicates that it has already overcome some biological barriers to cross-species transmission. This raises concerns that it may only need minor mutations to become more infectious in humans.
While China has denied past lab leak theories, the role of the Wuhan Institute of Virology in studying such viruses remains under scrutiny. Increased transparency and international collaboration in virus research are essential for early detection and response.
Public health experts stress that the global community must prioritize early warning systems and investment in zoonotic disease research. Strengthening laboratory biosecurity and monitoring bat virus reservoirs could help mitigate the risks of another pandemic.
The emergence of HKU5-CoV-2 underscores the ongoing risk of zoonotic disease transmission. Vigilance, global cooperation, and scientific preparedness are crucial to preventing future outbreaks.
