Members of the local Interact club walk through Birgunj, Nepal, reviewing the map and schedule before they assemble immunization booths on a subnational polio immunization day. Border towns with little regulation like Birgunj create high risk of the spread of the poliovirus. Subnational immunization days target strategic locations based on research by Rotary’s polio eradication partners, the World Health Organization, UNICEF, and the U.S. Centers for Disease Control.
