Researchers in China have discovered a new bat virus that closely resembles SARS-CoV-2, the virus responsible for COVID-19, raising fresh concerns about the potential for future pandemics. The virus, identified in horseshoe bats, was found to enter human cells using the same ACE2 receptor pathway as COVID-19, according to a new study published by Chinese scientists.
As reported by Bloomberg, the virus, tentatively named BtCoV-25, was identified in bat samples collected from southern China. Researchers noted that its spike protein structure is highly similar to SARS-CoV-2, meaning it has the capability to infect human cells.
A report by Reuters confirmed that experiments conducted in laboratory settings demonstrated the virus’s ability to bind to human ACE2 receptors, the same mechanism used by the virus that caused the COVID-19 pandemic. While there is no evidence yet that BtCoV-25 has infected humans, experts warn that close monitoring is crucial to prevent another global outbreak.
This discovery has reignited debates about the safety of bat-related virology research in China, particularly in light of ongoing investigations into the origins of COVID-19. The New York Post highlighted that the study was conducted in a laboratory setting, leading some to question whether such research poses unintended risks.
Newsweek reported that scientists are calling for increased transparency in bat virus research, with calls for international collaboration to monitor and study emerging zoonotic threats.
Despite public concern, virologists emphasize that BtCoV-25 has not been detected in human populations and is not currently considered an immediate public health risk. However, experts stress that early detection and surveillance remain critical in preventing potential spillover events.
With global health agencies monitoring the situation, the discovery of BtCoV-25 serves as a stark reminder of the ongoing risk posed by novel zoonotic viruses and the importance of continued vigilance in pandemic preparedness.
