WASHINGTON — Scientists have unraveled the genetic code of the common cold _ all 99 known strains of it, to be exact. But don't expect the feat to lead to a cure for the sniffling any time soon. It turns out that rhinoviruses are even more complicated than researchers originally thought.
In fact, the genetic blueprints showed that you can catch two separate strains of cold at the same time _ and those strains then can swap their genetic material inside...
