smallpox
leprosy
cholera
typhus
After vaccination campaigns throughout the 19th and 20th centuries, the WHO certified the eradication of smallpox in 1979. The fact that humans are the only reservoir for smallpox infection, and that carriers did not exist, played a significant role in the eradication of smallpox. So far, it is the only eradicated infectious human disease.
