In 1988, the World Health Assembly proposed the goal of global poliomyelitis eradication (polio). Subsequently, the implementation of the Global Polio Eradication Initiative by the World Health Organization (WHO) reduced the incidence of cases of wild polioviruses (WPVs) globally, from 350,000 estimated in 1988 to 2010 1288 cases reported. The Action Plan will also reduce the number of countries that have not blocked the transmission of WPV from> 125 countries to 4 countries (Afghanistan, India, Nigeria, Pakistan). Oral administration of live attenuated polio vaccine after the goal of eliminating all WPV transmission has been achieved
