Progress toward the 2012 measles elimination goal--Western Pacific Region, 1990-2008

In 2003, the World Health Organization (WHO) Regional Committee of the Western Pacific Region (WPR) formally declared a measles elimination goal, and in 2005, the committee established a target date of 2012 for regional measles elimination. Key strategies recommended by WHO for achievement of measles elimination include 1) very high (>or=95%) vaccination coverage with 2 doses of measles-containing vaccine (MCV1 and MCV2) through routine vaccination and/or supplemental immunization activities (SIAs); 2) high-quality case-based measles surveillance; and 3) access to an accredited measles laboratory network for testing of suspected measles cases and identification of measles virus genotypes. This report describes progress toward measles elimination in the WPR through 2008. Measles likely has been eliminated or nearly eliminated in 24 of the 37 countries and areas in the WPR (referred to in this report as countries). However, large numbers of measles cases continue to be reported from several countries. During 2008, a total of 131,441 confirmed measles cases (98.4 per million population) were reported from China and 11,015 cases (86.1 per million population) from Japan, two countries that account for 82% of the region's population and >97% of its confirmed measles cases. Intensified efforts by WPR countries, particularly China and Japan, will be required to achieve the 2012 goal.
