Overview
Because of polio eradication efforts, the number of countries where travelers are at risk for polio has decreased dramatically. The last documented case of wild polio virus-associated paralysis in a US resident traveling abroad occurred in 1986 in a 29-year-old vaccinated adult who had been traveling in South and Southeast Asia. In 2005, an unvaccinated US adult traveling abroad acquired vaccine-associated paralytic poliomyelitis after contact with an infant recently vaccinated with oral polio vaccine.

Transmission of wild poliovirus was interrupted in the United States in 1979, or possibly earlier. A polio eradication program conducted by the Pan American Health Organization led to elimination of polio in the Western Hemisphere in 1991. The Global Polio Eradication Program has dramatically reduced poliovirus transmission throughout the world.
