The last naturally occurring case of indigenous smallpox (Variola minor) was diagnosed in Ali Maow Maalin, a hospital cook in Merca, Somalia, on 26 October 1977. The last naturally occurring case of the more deadly Variola major had been detected in October 1975 in a two-year-old Bangladeshi girl, Rahima Banu.We have heard a lot about vaccines in the last few years. The fact is: vaccines work. The Variola major version of Small Pox has (had?) a mortality rate of 30-35% - out of every three people who got the virus, one died. In the 20th century, it is estimated that 300-500 million deaths were caused by small pox. Because of the small pox vaccine, no one gets this disease. Anywhere in the world.
