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.
