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.

Chinese scientists have discovered a new coronavirus in bats called HKU5-CoV-2. It shares similarities with SARS-CoV-2 and can infect human cells. Researchers are investigating its potential to spill over to 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.
