Although the Global Polio Eradication Initiative (GPEI) has faced sobering challenges in the past year, officials say it is moving forward in key political, technical, financial, and operational areas.

Stepped-up efforts to end the disease in the four endemic countries -- Afghanistan, India, Nigeria, and Pakistan -- are paying off, they say.

"Rotary International has played an extraordinarily special role [in the GPEI], not just as one of the initiators but in bringing financial resources, political advocacy, and volunteerism on the ground to getting the job done," said Dr. Bruce Aylward, director of the GPEI at the World Health Organization, speaking to the National Press Club in Washington, D.C., in June.

Aylward said that all levels of government in the four countries are committing unprecedented support for the polio eradication effort by monitoring the performance of immunization activities and holding local authorities accountable for the results.
