Polio was eliminated in the Americas by 1994. The disease was officially eliminated in 36 Western Pacific countries, including China and Australia in 2000. Europe was declared polio-free in 2002. Since January 2011, there were no reported cases of the disease in India, and hence in February 2012, the country was taken off the WHO list of polio endemic countries. If there are no cases of polio in the country for two more years, it will be declared as a polio-free country. As of 2008, polio remains endemic in only three countries: Nigeria, Pakistan, and Afghanistan. Although poliovirus transmission has been interrupted in much of the world, transmission of wild poliovirus does continue and creates an ongoing risk for the importation of wild poliovirus into previously polio-free regions. If importations of poliovirus occur, outbreaks of poliomyelitis may develop, especially in areas with low vaccination coverage and poor sanitation. As a result, high levels of vaccination coverage must be maintained. In November 2013, the World Health Organization announced a polio outbreak in Syria. In response, the Armenian government put out a notice asking Syrian Armenians under age 15 to get the polio vaccine. As of 2014, polio virus has spread out to ten countries mainly in Africa, Asia and the Middle East with Pakistan, Syria and Cameroon advising vaccinations to outbound travelers. In 2015, the World Health Organization announced a deal with the Taliban to encourage them to distribute the vaccine in areas they control.
