Scientists and security specialists are in the midst of a fierce debate over recent experiments on a strain of bird flu virus that made it more contagious.
The big question: Should the results be made public?
Critics say doing so could potentially reveal how to make powerful new bioweapons.
The H5N1 virus has been circulating among birds and other animals in recent years. It's also infected about 500 people. More than half died. But this dangerous virus has not caused widespread human disease because, so far, sick people haven't been very contagious
If the virus evolves to spread as easily between people as seasonal flu, however, it could cause a devastating global pandemic. So in an attempt to stay ahead of H5N1, scientists have been tweaking its genes in the lab to learn more about how this virus works, and what it is capable of.
In September, one scientist made a stunning announcement. At a flu conference held in Malta, he said he'd done a lab experiment that resulted in bird flu virus becoming highly contagious between ferrets — the animal model used to study human flu infection. It seemed that just five mutations did the trick.
It's just a bad idea for scientists to turn a lethal virus into a lethal and highly contagious virus. And it's a second bad idea for them to publish how they did it so others can copy it.
