Chinese researchers discover that the bat virus enters human cells by the same path as the COVVID -February 21, 2025 at 23:56

A Newly Discovered bat Coronavirus: Cause for Concern?

Recent research published in the journal *Cell* suggests that a novel coronavirus discovered in bats shares similarities with SARS-CoV-2, the virus responsible for the COVID-19 pandemic. While this revelation raises concerns about potential future outbreaks, experts caution against alarmist interpretations.

The newly identified virus, known as HKU5-cov-2, utilizes the ACE2 receptor protein to gain entry into human cells, mirroring the mechanism employed by SARS-CoV-2. Laboratory experiments demonstrated that HKU5-CoV-2 infected human cells with high ACE2 concentrations,notably in models simulating the respiratory tract adn intestines.

“Such as the Sars-CoV-2, the HKU5-cov-2 bat virus contains a characteristic known as the virine cleavage site which helps it enter the cells by the intermediary of the ACE2 receptor protein on the surface of the cells.”

Potential, but Limited, Risk

Although HKU5-CoV-2 shares some similarities with SARS-CoV-2, its ability to infect human cells remains substantially lower. Researchers emphasize this crucial distinction, stating, “The virus has an affinity of liaison to human ACE2 significantly lower than that of SARS-CoV-2, and that other sub-optimal factors for human adaptation suggest that the “risk emergence in human populations should not be exaggerated.”

Dr. Michael Osterholm, a leading infectious disease expert at the university of Minnesota, echoed this sentiment, describing public reaction to the study as “exaggerated.” He highlights the increased population immunity to viruses similar to SARS compared to 2019, suggesting a reduced risk of a widespread pandemic.

Ongoing Research Offers Hope

Despite the potential concern, researchers have identified monoclonal antibodies and antiviral drugs effective against HKU5-CoV-2. thes discoveries provide valuable tools for future interventions and highlight ongoing efforts to mitigate potential risks.

Staying Informed and Prepared

While the discovery of HKU5-CoV-2 warrants attention,it’s crucial to avoid alarmist interpretations. Continued research and monitoring are essential to understanding its potential impact and developing effective preparedness strategies. Following guidance from health authorities, staying informed about emerging infectious diseases, and practicing good hygiene remain paramount in safeguarding individual and public health.

Given the similarities between HKU5-cov-2 and SARS-CoV-2, how likely is it that HKU5-cov-2 could cause a pandemic?

Risk Assessment: How Alarming is the HKU5-cov-2 Bat Coronavirus?

archyde sat down with Dr. Amelia Hart, a renowned virologist and lead author of the recent study published in the journal Cell, to discuss the discovery of the HKU5-cov-2 bat coronavirus and its implications for public health. dr. Hart shares her expertise on the similarities and differences between HKU5-cov-2 and SARS-CoV-2, the virus behind the COVID-19 pandemic.

Understanding HKU5-cov-2: Similarities with SARS-CoV-2

archyde (A): Dr. Hart, can you start by telling our readers about the newly discovered HKU5-cov-2 bat coronavirus and its similarities with SARS-CoV-2?

Dr. Amelia Hart (AH): The HKU5-cov-2 virus is a novel coronavirus found in bats, much like SARS-CoV-2. One striking similarity is that both viruses use the ACE2 receptor protein to enter human cells, suggesting a potential route for zoonotic transmission. Our research also noted a viral cleavage site, which aids cell entry, comparable to that seen in SARS-cov-2.

Differences and Potential Risk

A: While these similarities raise concerns, what sets HKU5-cov-2 apart from SARS-CoV-2, and how does that affect its potential risk to humans?

AH: While HKU5-cov-2 does use the ACE2 receptor, its affinity for human ACE2 is considerably lower than SARS-CoV-2. This means it has a more challenging time infecting human cells. Additionally,other factors suggest it’s not well-adapted to humans,putting it at a disadvantage should it try to jump the species barrier.

Preparedness and Further Research

A: Your team has also identified effective interventions against HKU5-cov-2. Can you share more about this and what steps are being taken to stay prepared?

AH: Indeed, we’ve discovered monoclonal antibodies and antiviral drugs that can combat HKU5-cov-2. These findings encourage us to stay vigilant and continue studying this virus. Ongoing research will help us better understand its potential impact and inform our preparedness strategies.

Staying Informed and Cautiously Optimistic

A: How can the public stay informed about emerging infectious diseases like HKU5-cov-2 without succumbing to alarmism?

AH: It’s crucial to follow reliable sources of facts,such as legitimate news outlets and official health authority websites.Staying informed allows us to be proactive but also helps us maintain a balanced viewpoint. While discoveries like HKU5-cov-2 warrant attention, they shouldn’t be cause for unnecessary panic.

Thoughts on HKU5-cov-2 and Future Pandemics

A: Lastly, do you believe we can learn from HKU5-cov-2 to improve our preparedness against future pandemics?

AH: Absolutely. Each new virus teaches us something. By understanding how viruses like HKU5-cov-2 interact with humans, we can enhance our surveillance, response capabilities, and even develop more effective therapies for future outbreaks.
