New Bat Coronavirus Found: Could It Infect Humans?

Chinese researchers have discovered a new bat coronavirus that might spread to humans, raising concerns about future outbreaks. The virus, named HKU5-CoV-2, was found to interact with the same human receptor as SARS-CoV-2, which caused COVID-19.

Who Conducted the Study?

The research was led by Shi Zhengli, a well-known virologist often called “batwoman” for her work on bat viruses. The study included scientists from the Guangzhou Laboratory, Guangzhou Academy of Sciences, Wuhan University, and the Wuhan Institute of Virology. Their findings were published in the scientific journal Cell.

What Is HKU5-CoV-2?

• Part of the Merbecovirus family, which also includes MERS (Middle East respiratory syndrome).
• First found in Japanese pipistrelle bats in Hong Kong.
• Can attach to human ACE2 receptors, the same receptors SARS-CoV-2 uses to infect human cells.

Is It a Threat to Humans?

The virus can bind to human ACE2 receptors, but scientists say its ability to do so is much weaker than that of SARS-CoV-2. While there is a chance of it spreading from bats to humans directly or through another animal, researchers caution against panic.

A separate study from the University of Washington and Wuhan University also found that while HKU5-CoV-2 could attach to bat and mammal ACE2 receptors, it did not do so efficiently in humans.

Should We Be Concerned?

• Scientists believe HKU5-CoV-2 has a greater potential to jump between species than previous versions of the virus.
• The World Health Organization (WHO) is already monitoring merbecoviruses as part of pandemic preparedness.
• Researchers stress that ongoing surveillance is necessary to detect any potential risks early.

What About the Origins of COVID-19?

Shi Zhengli has denied allegations that the Wuhan Institute of Virology was responsible for the COVID-19 pandemic. While the exact origins remain unclear, many studies suggest the virus may have started in bats and jumped to humans through another animal.

Conclusion

While HKU5-CoV-2 is capable of infecting humans, experts say the risk is low for now. However, continuous research and monitoring are crucial to prevent potential future outbreaks.
