Smallpox was the first widespread disease to be eliminated by human intervention. Known as 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 disease until very recently. Its victims suffer 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 of the United Nations was authorized to initiate a global campaign to eradicate smallpox. The goal was to eliminate the disease in one decade. At the time, the disease posed a serious threat to people in more than thirty nations. Because similar projects for malaria and yellow fever had failed, few believed that smallpox could actually be eradicated but eleven years after the initial organization of the campaign, no cases were reported in the field.

          The strategy was not only to provide mass vaccinations but also to isolate patients with active smallpox in order to contain the spread of the disease and to break the chain of human transmission. Rewards for reporting smallpox assisted in motivating the public to aid health workers. One by one, each small-pox victim was sought out, removed from contact with others and treated. At the same time, the entire village where the victim had lived was vaccinated.

          By April of 1978 WHO officials announced that they had isolated the last known case of the disease but health workers continued to search for new cases for additional years to be completely sure. In May, 1980, a formal statement was made to the global community. Today smallpox is no longer a threat to humanity. Routine vaccinations have been stopped worldwide

The Census Counts!

          Every ten years there is a national census to count the number of people. The census counts the number of people in each area, the number of men and women, their ages, their profession, their family size and status. The census is the only way to count everyone. Its results are used by a great many people and are available to everyone. The census is useful; it helps to work  out present and future needs for housing by seeing how many people are housed now, or the sizes and ages of their families. In addition, the size of annual grants made by the Government to  public services depends largely on the numbers and needs of people in the area provided by the census. Furthermore, the census shows how many people have moved from one area to another and how the number of the local work force is changing.

          The census is taken in order to provide the figures about the nation as a whole. It does not give information about any named person, family or household. Therefore, names and addresses are needed on the forms but they are not fed into the computer. After the census, the forms with the names on are locked away and will not be released to anyone outside the Census Office for 100 years. The answers people give on their census forms will be treated in strict confidence. Everyone working on the census is sworn to secrecy and can be sued if he or she improperly reveals information
