Researchers have discovered a virus that could enter human cells in a similar way to COVID-19. But they caution it's much more poorly adapted to humans.

After Covid-19 and HMPV, a new bat coronavirus discovered in China has sparked concerns among health officials and has triggered another pandemic fear. The newly discovered virus, however, is yet to be detected in humans.

Experts note that HKU5-CoV-2 has a lower binding affinity to human ACE2 than SARS-CoV-2, and its ability to infect humans on a large scale remains uncertain. More research is needed to determine if it poses a serious health threat.
