New Coronavirus Identified in Bats: No Public Health Threat
In a groundbreaking discovery, scientists at the Wuhan Institute of Virology in China have identified a new strain of coronavirus, dubbed HKU5-CoV-2, in bats. This new coronavirus has the ability to enter human cells in a manner similar to SARS-CoV-2, the virus responsible for Covid-19. However, experts are quick to reassure the public that there is no immediate threat to public health.
Discovery and Mechanism
The discovery was detailed in a recent study published in the journal Cell. Researchers found the virus in anal swab samples from bats of the genus Pipistrellus. Laboratory experiments confirmed that HKU5-CoV-2 can infect human cells via the ACE2 receptor protein, the same pathway used by SARS-CoV-2. This new strain is part of the same family as the virus causing Middle East respiratory syndrome (MERS).
No Human Infections Reported
Despite its ability to enter human cells, there have been no reported infections in humans from HKU5-CoV-2. The US Centers for Disease Control and Prevention (CDC) has acknowledged the study but emphasized that there is no current reason for public concern. The CDC stated in an email to www.cnn.com that they will continue to monitor viral disease activity and provide updates to the public.
Expert Opinions and Context
Dr. Amira Roess, a professor of global health and epidemiology at George Mason University, emphasized that the findings should not cause panic. “Even the researchers themselves point out that this should not cause panic,” she told www.cnn.com. Roess highlighted the importance of such research in understanding potential risks and preparing for future outbreaks.
Dr. Alex Greninger, from the University of Washington Medical Center, added that there are likely many coronaviruses circulating in bats that can enter human cells. He pointed out that people should be more concerned about other coronaviruses causing the common cold, such as 229E, NL63, OC43, and HKU1, which are already endemic and causing illness.
Broader Implications and Global Health
Dr. Phoebe Lostroh, author of “Molecular and Cellular Biology of Viruses,” cautioned against sensationalist headlines about the new coronavirus causing the next pandemic. She believes that more attention should be given to other threats like avian flu, which has been impacting various mammals.
Roess also stressed the importance of global collaboration in monitoring and understanding viruses that could affect human health. She expressed concern about the US withdrawing from global health efforts under President Donald Trump, which could hinder such vital work.
Public Safety and Wildlife Interaction
The study serves as a reminder for the public to be cautious around wildlife, particularly bats. Roess noted that bats carry other pathogens that can be problematic for humans. “So respect these wild animals, don’t interact with them too much, because you could end up hurting them and yourself,” she advised.
Conclusion and Further Reading
The discovery of HKU5-CoV-2 in bats by the Wuhan Institute of Virology is a significant scientific finding, but it does not pose a current public health threat. As we continue to monitor this and other viruses, it’s crucial to stay informed about global health efforts and the potential risks from zoonotic diseases.
