Experts are anxious that bird flu could become airborne — and jump-start another pandemic

Could H5N1 bird flu become airborne and spread between people? Scientists say that’s still unknown. But, if the virus gains that ability, it could produce the next pandemic.

The virus has been tearing across the U.S. in recent months, resulting in the culling of millions of birds, sending egg prices skyrocketing, infecting dozens of humans, and killing one person in Louisiana.
