Wuhan, China – Scientists in Wuhan, China, have made an intriguing discovery – a new lineage of coronavirus found in bats that exhibits characteristics similar to SARS-CoV-2, the virus responsible for causing Covid-19, according to a recent study. This new coronavirus, named HKU5-CoV-2, can enter human cells through the ACE2 receptor protein, akin to how SARS-CoV-2 operates. Despite this, there have been no reported cases of human infection, and experts reassure that it does not pose a current threat to public health.
The study, which was recently published in the journal Cell, details how the coronavirus was identified in anal swab samples taken from a specific bat species. Even though lab experiments showed the virus’s ability to infect human cells, health authorities confirmed the absence of any human infections so far. The US Centers for Disease Control and Prevention, acknowledging the study, conveyed that there is currently no cause for concern regarding public health implications of the new coronavirus lineage.
Although HKU5-CoV-2 does not infect cells as efficiently as Covid-19, given its origin in the Wuhan Institute of Virology, the study has attracted significant attention. Dr. Amira Roess, a global health and epidemiology expert, stresses the importance of such research, emphasizing that understanding the potential risks posed by emerging viruses is crucial for proactive public health management.
While antiviral medications designed to combat SARS-CoV-2 have shown some effectiveness against HKU5-CoV-2 in experiments, experts like Dr. Alex Greninger of the University of Washington Medical Center urged the public not to overreact to the discovery of this new coronavirus lineage. He pointed out that there are numerous coronaviruses circulating in bat populations worldwide that have the ability to infect humans.
Dr. Phoebe Lostroh, an expert in virology, cautioned against sensationalizing headlines suggesting that HKU5-CoV-2 could lead to the next pandemic. She emphasized the importance of focusing on existing threats like avian flu and maintaining global health collaborations, a sentiment echoed by Dr. Roess. In an era of increasing isolationism, she emphasized the need for international cooperation in monitoring and combatting potential health crises.
As the study underscores the risk of zoonotic diseases transmitted from wildlife to humans, experts advise caution around wild animals like bats. Dr. Roess stresses the importance of respecting wildlife and avoiding unnecessary interactions that could lead to harm. This study serves as a timely reminder of the need for global vigilance and collaboration in tackling emerging health challenges.
