Chinese researchers have just discovered a novel bat coronavirus, HKU5-CoV-2, capable of infecting humans. This finding has elicited apprehensions on the potential for another epidemic.
The research team, directed by virologist Shi Zhengli at the Wuhan Institute of Virology, discovered that HKU5-CoV-2 may attach to the human ACE2 receptor, the identical mechanism employed by SARS-CoV-2, the virus that causes COVID-19.
This indicates that HKU5-CoV-2 may potentially be transmitted from animals to humans.

The virus presently exhibits reduced efficacy in penetrating human cells relative to SARS-CoV-2. Experts, including as Dr. Michael Osterholm, have observed that pre-existing population immunity to analogous SARS viruses and the virus’s diminished binding affinity to human ACE2 decrease the probability of substantial human adaptation and transmission.
The identification of HKU5-CoV-2 has rekindled debates over the genesis of pandemics and the function of high-security laboratories in the examination of hazardous viruses.
The Wuhan Institute of Virology has been the focal point of discussions over the origins of COVID-19, with multiple ideas proposing a potential laboratory leak. Nonetheless, a consensus on this issue remains elusive, and inquiries are continuing.

Although the detection of HKU5-CoV-2 is alarming, it is crucial to acknowledge that the virus has not been found in humans, and its potential to induce disease in humans is still unknown.
Researchers underscore the necessity for ongoing surveillance and investigation of these viruses to enhance comprehension of their potential hazards and to formulate measures for preventing future outbreaks.
The identification of HKU5-CoV-2 highlights the necessity for diligent surveillance of new viruses and proactive global cooperation to reduce the threat of future pandemics.
