Indicators to monitor measles elimination
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
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)

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.

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