Tremendous progress has been made in the global fight against polio since 1988, when the World Health Assembly resolved to eradicate the disease. The number of polio cases worldwide has decreased from 350 000 in 1988, to fewer than 800 cases in 2003. Three-quarters of all cases globally are linked to a handful of polio "hot spots" in Nigeria, Pakistan and India. At the end of 2003, six countries globally were still polio-endemic - Nigeria, India, Pakistan, Niger, Afghanistan and Egypt.
