Progress in global measles control, 2000?2010
In 1980, before widespread use of measles vaccine, an estimated 2.6 million measles deaths occurred worldwide.(1) Recognizing this burden, WHO and UNICEF developed an accelerated measles mortality reduction strategy of delivering 2 doses of measles-containing vaccine (MCV) to all children through routine services and supplementary immunization activities (SIAs), and improving disease surveillance.(2) Since implementation of this strategy began in 2001, the estimated number of measles deaths has fallen from 733 000 in 2000 to 164 000 in 2008.(3) At the 2010 World Health Assembly, member states endorsed the following targets to be met by 2015 as milestones towards eventual global measles eradication: (i) raise routine coverage with the first dose of MCV (MCV1) to ≥90% nationally and ≥80% in every district or equivalent administrative unit; (ii) reduce and maintain annual measles incidence to <5 cases per million; and (iii) reduce measles mortality by ≥95% in comparison with the estimated level in 2000.(4)
This report updates the previous statement on global measles control(3) and provides the first account of progress towards the 2015 targets. During 2000?2010, global MCV1 coverage increased from 72% to 85% and >1 billion children were vaccinated during measles SIAs. Globally reported measles cases decreased during 2000?2008. Subsequent large outbreaks led to an increase in reported cases in 2010, when 40% of member states did not meet the reported incidence target of <5 cases per million population. Key challenges must be overcome to meet the 2015 targets, including: 1) declining political and financial commitments to measles control; 2) failure to reach uniform high coverage with 2 doses of MCV through routine services or SIAs; and 3) inadequate subnational monitoring of MCV1 and MCV2 coverage data to guide interventions to increase coverage.
