LabNet Plays a Critical Role in Measles and
Rubella Control Programs
•Laboratory confirmation of suspected cases of measles and
rubella
•Detection of measles/rubella specific IgM in a serum or
oral fluid sample taken at first contact with patient
•Detection of viral RNA in an appropriately collected clinical
sample
•Isolation of virus in cell culture
•Genetic characterization of circulating strains for molecular
epidemiology analysis
•Measurement of population immunity

Structure of the WHO Global Measles and
Rubella Laboratory Network (LabNet)
•Multiple layers (similar to polio lab network)
Global Specialized Labs (CDC-Atlanta, HPA-London, NIID-Japan)
Regional Reference Labs (molecular biology, cell culture,
sequencing)
National Labs and sub national networks (sample collection, EIA,
some molecular testing and cell culture)
Management and supervision
Lab Coordinator at WHO Geneva (annual meeting)
GSL
Regional Lab Coordinators at WHO Regional Offices
Financial support
Host country/institute
RRL
NL
WHO, CDC, MR Initiative, Others
A global partnership to stop measles & rubella
Strengths of the LabNet Structure
Standardized testing and reporting structure
Excellent quality control at all levels
High quality data reported with stringent timeliness requirements
Use of lab data linked with epi data to drive public health
decisions
Local ownership and alignment with national public health
priorities
National laboratories are nominated by MOH in collaboration with
WHO
Integrated surveillance for measles and rubella and other VPDs
(e,g, Yellow Fever and Japanese Encephalitis)

Major Activities of the Measles and Rubella
LabNet
• Serologic testing for detection of measles
and rubella IgM
• Training and Capacity Building
• Standardization
• Quality Control
• Verification of Elimination
• Virologic Surveillance

Activity: Standardization

2012 WER nomenclature articles published
– Measles virus: published 2 March 2012
• Genotype D11 was verified
• Decisions were made on subgenotypes
• 6 genotypes not detected since 2000
• 5 genotypes not detected since 2006
• Protocols were made accessible on WHO genotype database
– Mumps virus: published 1 June 2012
• Nomenclature and genotype classification
• Reference strains revised
• Global distribution of genotypes reported, including map
– Rubella virus Nomenclature update
• planned for late 2012 - early 2013
A global partnership to stop measles & rubella
Activity: Quality Assurance
 A proficiency testing (PT) panel for serology is sent
annually from VIDRL, in Melbourne
– 180 laboratories participating with excellent results
 A PT for molecular techniques is being planned
 Regular laboratory accreditation processes including
site visits

Meeting the Need for Enhanced Surveillance
 Oral fluid samples (OF)
– AFR
• 5 country trial: Zimbabwe, Malawi, Kenya, Benin, CIV
– SEAR
• India and Sri Lanka good correlation with serum but
highlighted need for adequate training of surveillance staff
– EUR
• France tested >3500 OFs in recent measles outbreak
 Point of care
– Refinements of sample type and field testing is
underway
WHO Vaccine Preventable Disease Lab Network
Activity: Verification of Elimination of Measles
and Rubella
• Monitoring of surveillance performance indicators
• ≥80% of confirmed outbreaks with a sample for
virus detection and genotyping
• Determining population immunity using
serosurveys to validate reported vaccination
coverage
A global partnership to stop measles & rubella
Activity: Virologic Surveillance for
Measles and Rubella
Molecular epidemiology is a key component of the verification
process for measles and rubella elimination
A criterion for elimination is the absence of an
endemic genotype for one year
Genetic data in conjunction with standard epidemiologic
information can be used to track transmission patterns and
identify sources of infection

Measles and Rubella LabNet Challenges (1)
Financial support to maintain laboratory activities
Financial support to expand case based surveillance for measles
and rubella (especially GAVI countries)
Staff turnover (RLCs, GLC) and training needs
Need to maintain and expand sequence databases
Better use of date by linking epi and lab data in Africa
Expansion in India
Introduction of new methods (Molecular)
Maintain and expand QC/QA Program
Integration with surveillance for other VPDs
Development of testing strategies for low incidence settings

Measles and Rubella LabNet Challenges (2)
 Molecular surveillance plays a vital role in
monitoring progress with rubella control and in
verification of elimination
 Large gaps in surveillance for rubella virus
 Baseline data should be collected well before
acceleration of activities for control
 Global rubella sequence database (RubeNS)
under development
 Enhance laboratory capacity in GAVI eligible
countries

Summary
 Strong capacity: >200,000 IgM tests, 3,000 measles
sequences and 330 rubella sequences annually
 Proficiency high -- closely monitored and maintained
 Molecular surveillance is becoming increasingly important
for monitoring progress of elimination and verification
 Still gaps in molecular surveillance, especially for rubella
 Financial support for the LabNet is tenuous
 Search for new coordinator is ongoing
