Polio rose to epidemic proportions in the United States with more than 21,000 cases reported in 1952 [3]. With the development of effective vaccines against the virus during the 1950s the incidence of poliomyelitis went in decline and the last case of wild-type virus reported in the United States was in 1979.
Although nearly 400,000 paralyzed polio survivors still live in the US, the number of new cases is essentially zero among US residents, with only 1 reported case from 2004 to â¦ 2009. The actual number of infections may be higher (up to a dozen per year) if immigrant cases are considered.
