When conman Captain Jack Harkness planted a Chula ambulance in 1941 London, the Chula nanogenes, who had never previously encountered humans, infected a dying human boy named Jamie caught in the London Blitz. Assuming that the gas mask he was wearing was part of his face, they "healed" him, and unintentionally created the "Empty Child," a "zombie" based on Jamie's characteristics and injuries at death. Thus, everyone affected by the plague inherited a gas mask in place of their faces, severe head trauma on the left side, partial collapse of the chest cavity of the right, and a gash on the back of their right hands.
The nanogenes also gave the child the standard abilities of Chula soldiers, specifically super-human strength, telepathic abilities and the ability to communicate using anything with a speaker grill. The Empty Child still had a child-like mentality and escaped to search for its mother.
The Empty Child compulsively searched for his mother, and, in doing so, contaminated other humans with the nanogenes. Those who were infected did likewise so that the nanogenes spread in a fashion similar to a virus. The child, and all victims of it, were infamous for repeating the phrase, "Are you my Mummy?", endlessly. At first, people were only infected if touched by someone who was already infected, though it soon became airborne.
The Empty Child plague was finally stopped when the Ninth Doctor reunited the Empty Child with his mother and the nanogenes understood, recognising the mother as the superior source, the proper sequence for a human of that era. Jamie was fully restored by the nanogenes and the Doctor sent the reprogramed nanogenes to the other infected humans. Now knowing what a proper human was supposed to look like the nanogenes restored the people back to their original selves and repaired all of their injuries and aliments in the process. The Doctor would later state to Rose Tyler that he programed the nanogenes to shut themselves down once they repaired the damage they created to stop them from being a problem again in the future.

The Tenth Doctor, after having assumed the identity of John Smith, drew a picture of two Empty Child victims in A Journal of Impossible Things. (TV: Human Nature) When later given a gas mask during Sontaran invasion of Earth, the Tenth Doctor jokingly asked, "Are you my mummy?," as a reference to these events. (TV: The Poison Sky) When confronted with the Foretold, a mummy on the Orient Express in space, the Twelfth Doctor attempting to find out how and why the mummy was present, blurted out, "Are you my mummy?".
