There’s a central question that many scientists face: How can scientific discoveries drive humanity’s progress without posing a dire risk to it? As virus experts, we’re committed to research that uncovers pandemic threats and helps protect people from them. But we are concerned about how some scientists are experimenting with viruses in ways that could put all of us in harm’s way.

In a study published in the scientific journal Cell, a group of researchers reported the discovery of a coronavirus in bats that has the potential to spread to humans.

In a series of experiments, the scientists show that this virus, HKU5-CoV-2, can efficiently infect cells of humans and a wide range of other animal cells. The findings raise the possibility that humans and other animals could be infected by this virus. This coronavirus belongs to a subgroup of viruses that are classified alongside the one that causes MERS and that can have fatality rates far higher than that of the virus that caused the Covid pandemic.

The Wuhan Institute of Virology, where many of the researchers work or have worked, is at the center of the controversy regarding the origin of the Covid pandemic. We do not imply that the institute is responsible for the Covid pandemic, nor do we have any certainty that this newly discovered virus has the potential to cause the next one. What worries us is the insufficient safety precautions the researchers took when studying this coronavirus.

Research laboratories have different levels of security, based on its categorization on a biosafety level scale,66jogo.com from BSL-1, the lowest, to BSL-4. Lower-security labs are used for studying infectious agents that either don’t cause disease in people or pose only moderate risk. The higher-security laboratories are for studying pathogens that can spread in the air and have the potential to cause lethal infections.

BSL-4 labs are the ones featured in movies where scientists walk around in what look like spacesuits with air hoses and shower in decontamination chambers when their work is done. BSL-3 labs limit access to specifically trained staff members, have locking double doors for enhanced security and specific air handling and sterilization systems. Workers wear head-to-toe personal protective equipment and are under medical surveillance for signs of laboratory-acquired infection that could pose a risk to others.
