• Resumen

  • Smallpox remains the only human disease to have been deliberately eradicated from the face of the Earth. Defined as the complete and permanent reduction of a disease to zero new cases at a global level, eradication is a challenge to say the least. Even more mpressive is the speed with which it was achieved. In 1967, smallpox was responsible for 1.5 million deaths; 10 years later it was gone although the official declaration came in 1980. Here, Senthilingam investigates how people wipe a disease off the face of a planet.
