Descolada

From Orson Scott Card Wiki

"Un-gluer", The Descolada is a superintelligent virus that has infected all of the inhabitants of Lusitania. The pequeninos cannot live without it, and life alien to Lusitania, is threatened to be wiped-out. Eventually, on the first trip to the Outside, Ela created the Recolada, the "Re-gluer" and replaces the descolada with a less threatening virus.
