New Bat Coronavirus HKU5-CoV-2 Found in China Shows Potential for Human Infection

Researchers identify a bat virus capable of using the same receptor as COVID-19, raising concerns about zoonotic transmission risks.

The newly discovered HKU5-CoV-2 virus belongs to the merbecovirus subgenus, which includes the MERS virus, and was identified in bats by researchers in China.
The virus can bind to the human ACE2 receptor, the same entry point used by SARS-CoV-2, though its ability to infect humans is currently less efficient.
Lab studies confirmed the virus can infect human cells and human organ models, but no cases of human infection have been reported outside laboratory conditions.
Experts emphasize that while the virus poses a zoonotic risk, the likelihood of a new pandemic from HKU5-CoV-2 is considered low at this time.
The discovery underscores the importance of continued surveillance of emerging viruses, particularly those with potential for cross-species transmission.
