A new bat coronavirus, named HKU5-CoV-2, has been identified in China, sparking worries about the possibility of another pandemic. This virus shares similarities with SARS-CoV-2, the virus responsible for COVID-19, as it targets the same human receptor, angiotensin-converting enzyme (ACE2). Researchers have warned that HKU5-CoV-2 has the potential for human-to-human and cross-species transmission.
The research team, led by Zheng-Li Shi at Guangzhou Laboratory in Guangdong, China, discovered this new coronavirus. Shi, also known as the 'batwoman,' previously worked at the Wuhan Institute of Virology, which has been under scrutiny as a potential source of the COVID-19 outbreak.
Published in the scientific journal Cell on Feb. 18, the study highlighted the zoonotic risk posed by HKU5-CoV-2. The virus was found to infect human cells and artificial lung and intestine tissues in laboratory experiments.
Dr. Marc Siegel, a clinical professor of medicine at NYU Langone Health, emphasized that bats are carriers of various coronaviruses. He explained that HKU5-CoV-2 is related to the MERS virus, which caused a limited outbreak in humans in 2012. While the new coronavirus can bind to human receptors, the risk of transmission remains low compared to SARS-CoV-2.
Siegel stressed the importance of not succumbing to fear and panic, despite the ongoing COVID-19 pandemic. He suggested the establishment of an international consortium of scientists to enhance global preparedness and response to potential pandemics.
While the risk of HKU5-CoV-2 causing a pandemic is deemed low, continued research and vigilance are essential to monitor and mitigate any potential threats. The scientific community's collaboration and transparency are crucial in addressing emerging infectious diseases and safeguarding public health.
