A new bat coronavirus, HKU5-CoV-2, has been discovered in China, raising concerns about the potential for another pandemic. The virus, similar to SARS-CoV-2, targets the same human receptor, angiotensin-converting enzyme (ACE2), which could lead to human-to-human or cross-species transmission.
Researchers from the Guangzhou Laboratory and other institutions found that HKU5-CoV-2 can infect human cells and artificially grown lung and intestine tissues. While Dr. Marc Siegel, a clinical professor of medicine at NYU Langone Health, notes that bats harbor multiple coronaviruses, he emphasizes that the risk of infection remains “very low” due to the virus’s weaker binding and lower power compared to SARS-CoV-2.
However, experts warn that zoonotic spillover is possible, where the virus could infect humans and spread through human-to-human contact. Siegel stresses that while the COVID pandemic was severe, it does not mean another is imminent. He advocates for international cooperation and global protection measures, citing studies like this one as a step in the right direction.
The discovery of HKU5-CoV-2 highlights the need for ongoing research into bat coronaviruses and their potential risks to human health. As Siegel notes, more transparency and collaboration are essential in addressing these concerns.
