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.

The virus belongs to the merbecovirus subgenus, which includes the MERS-CoV virus responsible for Middle East respiratory syndrome (MERS). MERS, first detected in 2012, spreads from camels to humans and has a high fatality rate.
