Smallpox is one of the only diseases to have been eradicated by sustained human effort. But before it was eliminated in 1977, it claimed an estimated 300 million lives in the 20th century alone. The highly contagious disease was characterised by fever and a spotted skin rash. Although most people recovered, about three in every 10 people died from smallpox.One of the most challenging places when it came to eradicating smallpox was India, largely because of its size, geographic complexity and population. Despite the Indian government initiating its own national campaign to eliminate smallpox in 1962, vaccinating the entire population was painfully slow and challenging – especially with the country’s rapidly growing population.
