The Last Natural Case of Smallpox Infection

The last natural case of smallpox infection occurred in Somalia on October 31st, 1977. It happened in a 23-year-old cook named Ali Mao Malin who had actually once worked as a smallpox vaccinator despite never having been vaccinated himself. Once news of his infection reached the WHO, a team was sent to vaccinate the around 90 people who had come into contact with him. The world was declared smallpox free on my 8th, 1980.
