A highly contagious viral disease, it broke out in Europe, causing the deaths of millions of people until the vaccination was invented by Edward Jenner around 1800. In many nations, it was a terror, a fatal desease until very recently. Its victims suffered high fever, vomiting and painful, itchy, pustules that left scars. In villages and cities all over the world, people were worried about suffering smallpox.In May, 1966, the World Health Organization (WHO), an agency ofthe UN, was set up to start a global campaign to eradicate small pox in one decade. At the time, the disease caused a serious threat to people in thirty nations. More than 700 doctors, nurses, scientists and other personels from WHO with about 200.000 health workers in the nations joined the battle against the disease. Very few peole believed that a disease as widespread as smallpox could actually be eradicated but eleven years after the anti- smallpox campaign, no smallpox cases were reported.First, there was an education campaign so that people in all countries could know more about how the disease spread and took active part in the fight against smallpox. Other steps included not only providing mass vaccination but also isolating patients with active smallpox in order to limit the spread of the disease. Money rewards would be given to one informing about smallpox cases to motivate the public to help health workers. One by one, each smallpox victim was found out and treated. At the same time, the entire village where the victim had lived was vaccinated.By April of 1978, WHO officals announced that they had isolated the last case of smallpox but health workers continued to search for new cases for two additional years to be completely sure that there weren’t any existed smallpox cases. In May 1980 WHO formally stated that the smallpox was completely eradicated. Today smallpox is no longer a threat to humanity. Routine vaccinations have been stopped worldwide.
