Scientists at China Wuhan Institute of Virology have identified a new bat coronavirus named HKU5-CoV-2, which shares similarities with Covid-19 and Middle East Respiratory Syndrome (MERS). However, researchers emphasize that this virus has not been found in humans and was detected only in a laboratory setting.
Published in the journal Cell and reported by Reuters, the discovery has drawn attention from the scientific community and investors, causing a spike in vaccine manufacturers’ stock prices. Despite concerns, experts clarify that HKU5-CoV-2 does not infect human cells as easily as SARS-CoV-2, reducing its immediate risk to human populations.
How Does HKU5-CoV-2 Spread?
HKU5-CoV-2 originates from the same coronavirus family as Covid-19 and MERS. Like SARS-CoV-2, it contains a furin cleavage site, which enables it to enter cells through the ACE2 receptor, a key protein found in human respiratory and intestinal tissues.
Laboratory experiments showed that HKU5-CoV-2 could infect human cells with high ACE2 levels, particularly in models of human intestines and airways. However, scientists remain uncertain about its animal-to-human transmission.
Not all coronaviruses can infect humans, and HKU5-CoV-2 is still under study to determine its potential risk.
What Are the Symptoms of HKU5-CoV-2?
Though HKU5-CoV-2 has not been detected in humans, coronaviruses from the same family, including MERS, cause symptoms such as:
- Fever and chills
- Cough and congestion
- Fatigue and loss of appetite
- Sneezing and shortness of breath
- Diarrhea and vomiting
Is HKU5-CoV-2 a Cause for Concern?
According to Michael Osterholm, an infectious disease expert at the University of Minnesota, concerns over HKU5-CoV-2 are overblown. While its genetic makeup resembles Covid-19, there is no evidence suggesting that it can easily spread to or among humans.
How to Stay Safe?
Although this virus does not currently pose a risk to humans, health experts, including the CDC (Centers for Disease Control and Prevention), recommend basic preventive measures:
- Stay updated on vaccinations
- Practice good hygiene, including frequent handwashing
- Wear masks in high-risk environments
- Monitor symptoms and seek medical advice if needed
