  1. Measles in EMR 7th Annual Meeting of Partners for Measles AdvocacyWashington, 2007

  2. Outline • Regional progress in measles elimination • Key constraints • Indicators to monitor measles elimination in EMR

  3. Strategy for Measles Mortality Reduction and Elimination in EMRO • Routine infant immunization • > 90% coverage MCV1 in all districts • Catch-up vaccination • susceptible cohorts • Second dose of measles vaccine either through a 2 dose schedule or follow-up SIAs • > 90% coverage in all districts • Case-based surveillance • Optimized case management

  12. Recommended SIAs in EMR that are not Planned; 2007-08 . Catch-up campaigns Follow-up campaigns High-risk/mop-up campaigns

  13. Pakistan Catch-up Campaign • Phase 1 • Mar 2007 • 1 district in 4 provinces (2.6M target) • Phase 2 • Jul 2007 • parts of NWFP, Baluchistan, Fana, AJK (8.2M) • Phase 3 • Aug 2007 • Finish NWFP, Bal, AJK (5.3M) • Phase 4 • Nov 2007 (13.6M) • Sindh • Phase 5 • 1st Qtr ’08 (34.0M) • Punjab

  14. Second Dose of Measles Immunization in EMRO, 2005 Palestine • 19 countries with 2 dose schedule • 12 at 12 –24 mos • 7 at 4-6 yrs • 16 use MMR • 1 countries with periodic SIAs • 2 countries with periodic SIAs and 2 dose schedule • 2 countries with no second opportunity Bahrain Routine second dose 1 dose + SIAs 2 doses + SIAs 1 dose schedule

  15. Measles Surveillance in EMRO Palestine Bahrain Case based (17) Case-based, needs to be improved (3) Aggregate data (2)

  16. Status of Measles Reporting in EMRO, Jan-Dec, 2006* * Provisional data, reporting not complete

  17. Monthly Bulletin • Case counts by country and case classification • Key indicators • Mapping through EPIINFO • Website • Monitoring of susceptibility profiles Feedback of Surveillance and Coverage Data

  18. Outline • Regional progress in measles elimination • Key constraints • Indicators to monitor measles elimination in EMR

  19. Lack of national support for elimination • Competing priorities • Insecurity • Resource mobilization for non-GAVI countries • Egypt, Morocco, Syria • Failure of keep-up strategies • Limited use of surveillance data Key Constraints in Regional Elimination

  20. Catch-up campaigns 12-18 yrs6-13 yrs Measles Case Counts and Vaccination Coverage, 1988-2005, Saudi Arabia Coverage

  21. Age Distribution of Measles Cases in Saudi Arabia, Jan-Dec 2006 < 1 yr 1 to 4 yrs 5 to 9 yrs 10 to 14 yrs 15-20 yrs > 20 yrs n=697 5% vaccinated

  22. Syria (n=462) 48% vaccinated Egypt n=998 96% vaccinated Qatar (n=108) 54% vaccinated Lebanon (n=843) 20% vaccinated Age Distribution and Vaccination Status of Measles Cases in Selected EMR Countries, Jan-Dec 2006 < 1 yr 1 to 4 yrs 5 to 9 yrs 10 to 14 yrs 15-20 yrs > 20 yrs

  23. Geographic Distribution of Measles Cases, Jan-Dec ‘06

  24. Outline • Regional progress in measles elimination • Key constraints • Indicatorsto monitor measles elimination

  25. Indicators for Measles Elimination Recommendations from EMR-TAG, 2006 • Completeness of reporting • Indicator: > 80% of districts reporting on a monthly basis • Sensitivity of reporting system • Indicator: At least 2 suspect cases (excluding lab and epi-confirmed measles and rubella) per 100,000 population at the national level. • Adequacy of laboratory testing • Indicator: > 80% of suspect measles cases are tested for measles IgM antibody, excluding cases epidemiologically linked to a laboratory confirmed case from the denominator

  26. Indicators for Measles Elimination Recommendations from EMR-TAG, 2006 • Adequacy of epidemiologic investigation* • Indicator: > 80% of suspect measles cases have an adequate epidemiologic investigation*. • Adequacy of laboratory testing • Indicator: > 80% of measles virus outbreaks and chains of transmission chains (outbreaks) have sufficient* samples for viral isolation • *An adequate investigation includes at a minimum the suspect cases with all of the following data elements; date of rash onset, specimen collection, date of specimen collection, vaccination status, date of last vaccination, age, and district)

  27. Completeness of Reporting to Regional Office, Countries Reporting on a Monthly Basis, 2006 Palestine Bahrain Reporting on a timely basis (n=16) Delayed reporting (n=4) Inconsistent/not reporting (2 countries)

  28. Suspect Cases+ per 100,000 in EMR, Jan-Dec-2006* Proposed regional target 2/100,000 + Suspect cases – lab and epi confirmed cases * Adjusted for annualized rate

  29. Serologic Testing of Suspect Cases (Jan-Dec ’06, EMR)Indicator: > 80% of suspect cases with testing Palestine Bahrain > 80% of suspect cases (10 countries) 50-80% (3 countries) < 50% (7 countries) Not reporting (2 countries)

  30. Adequacy of Epidemiologic Investigation, Jan-Dec ’06 EMR Indicator: >80% of measles case reports with complete investigation Palestine Bahrain > 80% (6 countries) 50-80% (5 countries) < 50% (6 countries) Not reporting (5 countries)

  31. Recommended Criteria for Measles Elimination EMR-TAG, 2006 • Measles incidence of < 1 confirmed case per million per year, excluding cases confirmed as imported. • All districts with > 90% vaccination coverage for the first dose of measles vaccine and 95% coverage national coverage for the second dose. • 90% of outbreaks are < 10 cases in size • Epidemiologic and laboratory data indicate that measles viruses are imported.

  32. Measles Cases per Million in EMR, Jan-Dec-2006* * provisional

  33. MCV1 Coverage* Indicator: > 90% coverage in all districts Palestine Bahrain MCV1 > 90% in all districts (7 countries) MCV1 > 80% in all districts (2 countries) MCV1 > 50% in all districts (4 countries) MCV1 < 50% in some districts (8 countries) * Based on 2005 JRF, data is unavailable for Lebanon

  34. Summary • Considerable progress in mortality reduction • Pak campaign will reduce further • Few countries are close to elimination • Several countries with large outbreaks • Failure of “keep-up” strategies • SIAs are playing an important role to achieve elimination

  35. Summary • Surveillance is improving • Impact on program activities • Countries have accepted agreed upon indicators • RTAG will address issue of “certification”

  36. Priority Activities • Advocacy • Raising awareness of national health authorities • Development of country-level TAGs • Certification process? • Surveillance • Revisit regional reporting format • Outbreak surveillance • Source of infection • Genotyping • Achieving high population-based immunity • Better monitoring of routine EPI data • Achieving and monitoring high MCV2 coverage • Monitoring susceptibility profiles at sub-national levels
