Global LabNet Meeting Participants

Implications for LabNet in achieving Elimination Indicators (WER No 49, 2010, 85, ) ELISA IgM testing: – ≥ 2/100,000 (non-measles rash/fever cases) per year & ≥ 80% serum samples collected Workload increase estimated extra ~50,000 cases / yr Workload increase estimated extra ~50,000 cases / yr Mainly Pakistan and India moving to case based surveillance Mainly Pakistan and India moving to case based surveillance India planning 3 new labs 2011 (~$100,000) India planning 3 new labs 2011 (~$100,000) LabNet has proven surge capacity LabNet has proven surge capacity –Measles IgM cost ~ $ per sample (depending on batch size) –Rubella IgM cost ~ $ per sample WHO Vaccine Preventable Disease Lab Network 4

Implications for LabNet in achieving Elimination Indicators (WER No 49, 2010, 85, ) Virus detection: –Measles elimination: The absence of endemic measles cases: –Re-establishment of endemicity: continuous transmission of indigenous measles virus for a period of > 12 months: –>80% of laboratory-confirmed measles outbreaks have adequate samples for virus characterization in an accredited lab WHO Vaccine Preventable Disease Lab Network 5

Current challenges for improving molecular surveillance African region: –Building molecular capacity in Uganda and CIV Molecular surveillance gaps: –Sequencing capacity available but limited sample collection for virus detection –Enhanced molecular surveillance using Oral fluid Trials in India, Benin, CIV, Kenya, Malawi and Zimbabwe Trials in India, Benin, CIV, Kenya, Malawi and Zimbabwe WHO Vaccine Preventable Disease Lab Network 6

Molecular surveillance recommendations Reference and sequencing laboratories –determine their capacity to reach surveillance indicators –determine the additional resources needed Laboratory and field surveillance programmes –collaborate to enhance molecular surveillance Greater molecular capacity needed with documented accuracy –training programmes –molecular proficiency programme established

Genotype B3 sequences from Libya, Tunisia and Sudan should be considered as a third cluster in genotype B3. Virus to be provided by Institut Pasteur de Tunis. Reference viruses for Rubella genotypes 1h, 1i, and 1j have been identified. These viruses to deposited in the WHO rubella virus strain banks The recent changes in the list of recognized rubella and measles genotypes should be published in the WER A steering committee to be formed to review and refine the protocols for accepting and distributing sequence information via MeaNS and the WHO Database WHO should develop a mechanism for rapidly notifying LabNet of important developments such as detection of a new lineage or genotype WHO Vaccine Preventable Disease Lab Network 17

Quality Assurance Recommendations More comprehensive analysis of IgM proficiency testing and reporting Introduction of proficiency test for molecular techniques More comprehensive training & post training assessments WHO Vaccine Preventable Disease Lab Network 22

New Procedures

Documentation of new procedures WHO Vaccine Preventable Disease Lab Network Alternative samples to serum for measles and rubella New sequencing primers for measles and rubella Real time PCR; M & R Validated and in process of implementation In process of validation Rapid Point of care assays M & R PCR QC programme Standards for measles serosurvey 25 QC for Oral fluid

Funding

Current LabNet Estimated Costs WHO Vaccine Preventable Disease Lab Network 27 Estimated shortfall $1,300,000

Funding recommendations LabNet should endeavour to find additional resources and new partners Countries encouraged to include laboratory support in their surveillance budgets Additional funds for training, to: –Maintain the current high level of LabNet performance –Strengthen sequencing capacity

Summary LabNet has capability to meet increased surveillance needs –Some capacity will need to be developed Capacity building and extra testing comes at a cost, not all of which is realised
