The Horn of Africa still remains vulnerable to a polio outbreak despite most nations inching closer to eradicating the disease from the face of the earth.
According to Unicef, the countries that need close monitoring are Kenya, Uganda, South Sudan and Somalia, due to the high numbers of children who miss vaccination every year.
