Pakistan and Afghanistan are the only two countries in the region, which are not polio free. Nigeria is the third country in the list of countries not free from polio. Pakistan's decision is likely to affect Afghans, who want to come to Pakistan for education, treatment, business and to meet relatives. Pakistan had introduced visas and passports for Afghan nationals in June 2016 over concerns that free border movement would enable the militants to enter Pakistan for violence.
