Progress toward poliomyelitis eradication in the Eastern Mediterranean Region of the World Health Organization.

The Eastern Mediterranean Region (EMR) of the World Health Organization has made substantial progress toward eradicating poliomyelitis. From 1988 to 1995, the number of confirmed cases of polio decreased 66%, from 2342 to 789. National immunization days were conducted in 18 (78%) of the 23 countries in 1995, representing 88% of the regional population. By 1995, 20 countries (87%) in the EMR had established systems for reporting acute flaccid paralysis (AFP), 20 (87%) were investigating AFP or polio cases epidemiologically, 18 (78%) had initiated follow-up at 60 days to confirm or discard suspected polio cases, 7 (30%) had achieved nonpolio AFP rates of > or = 1.0/100,000 children <15 years of age (a measure of the sensitivity of surveillance), and 16 (70%) had made laboratory investigations of polio cases for 1281 (74%) of the 1715 AFP cases reported in the EMR. Despite significant progress, the success of the polio eradication initiative in the EMR will depend on finding solutions to a number of technical, managerial, political, and financial challenges.
