Polio is a crippling and deadly viral disease. Through an impressive effort involving millions of people and billions of doses of oral polio vaccine, the Global Polio Eradication Initiative (GPEI) has interrupted polio transmission in all but three countries: Pakistan, Afghanistan, and Nigeria .

Rates of routine immunization, which would provide a populationwide firewall against polio, remain low .

But militant groups have begun to target these workers, breaking down the front line of defense against polio
