A Chinese team of virologists has discovered a new bat coronavirus that can infect human cells, raising concerns about potential animal-to-human transmission. The virus, a new lineage of the HKU5 coronavirus, uses the same human receptor as the virus that causes COVID-19. The study, led by Shi Zhengli, a prominent virologist at the Wuhan Institute of Virology, was published in the journal Cell. The discovery comes amid ongoing scrutiny of the Wuhan lab, which was previously accused of being the source of the COVID-19 pandemic. The Chinese government has denied any involvement in the virus's origin and insists that the Wuhan lab never engaged in gain-of-function studies on coronaviruses.
