The first outbreak of polio in the United States in 26 years occurred earlier this fall in an Amish community in central Minnesota, state and federal health officials reported yesterday.
Four children have been infected with the virus, although none has become paralyzed. The Amish typically decline to vaccinate their children. The last large outbreak of polio occurred in numerous Amish communities in several states in 1979.
The outbreak poses little threat to children outside the Amish community. About 98 percent of Minnesota's children are vaccinated against polio, said Harry Hull, the state epidemiologist.
The outbreak was discovered by chance on Sept. 29 after the first child -- a 7-month-old infant with a severe immune deficiency disease -- was tested for another problem in August. Yesterday's announcement reveals the microbe is circulating among healthy children in the isolated community, which has about 200 people in 24 families. <snip>
