![Page 17: Deliberations of the 23 rd IEAG 13 - 14 July 2011](https://reader036.vdocument.in/reader036/viewer/2022062408/56649efe5503460f94c13849/html5/thumbnails/17.jpg)
4 essential elements of risk management:
1. enhance routine OPV3, esp. in west UP, WB
2. enhance surveillance
3. ensure outbreak preparedness plans
4. extra OPV campaigns in highest risk areas
IEAG Conclusion 4:
![Page 18: Deliberations of the 23 rd IEAG 13 - 14 July 2011](https://reader036.vdocument.in/reader036/viewer/2022062408/56649efe5503460f94c13849/html5/thumbnails/18.jpg)

Routine Immunization:1. Particular attention to those reservoir or
amplication areas with lagging OPV3 (e.g. west UP, West Bengal).
2. Re-emphasize critical importance of ANM and Medical Officer vacancies in these areas.
3. Continue to build on convergence of polio & routine EPI activities (e.g. microplanning, communications, migrant/marginalized pops).
Risk Management 1
![Page 20: Deliberations of the 23 rd IEAG 13 - 14 July 2011](https://reader036.vdocument.in/reader036/viewer/2022062408/56649efe5503460f94c13849/html5/thumbnails/20.jpg)
Surveillance:1. complete the planned serosurvey (August)
2. expand environmental sampling as planned
3. enhance surveillance among migrant populations (e.g. enrolling appropriate reporting sites/informers)
4. sustain state-level reviews for quality assurance (esp. reservoirs/amplification areas)

Emergency Preparedness Plans:1. ensure all states complete plans & that these are
shared/reviewed centrally
2. ensure the identified risk areas have follow-up risk mitigation activities
3. conduct simulation exercises in highest risk areas in August 2011 (reservoirs, recently infected areas & amplification sites)
4. Ensure minimum buffer stock of 40 million bOPV and 10 million tOPV doses (review 6 monthly)

IEAG Conclusion 5:
Additional OPV campaigns are
essential to protect the 'reservoir'
and 'amplication' areas going into
the 2011 high season.

Q6: How should the current
communication gains be maintained & what
are the specific communication challenges
at this stage of polio eradication?
![Page 28: Deliberations of the 23 rd IEAG 13 - 14 July 2011](https://reader036.vdocument.in/reader036/viewer/2022062408/56649efe5503460f94c13849/html5/thumbnails/28.jpg)
IEAG Conclusion 6:The current plan to maintain communications
gains is endorsed, recognizing that the
greatest challenges are (a) ensuring rapid,
high-quality emergency response & (b)
building on the polio capacity to improve
child health.
![Page 29: Deliberations of the 23 rd IEAG 13 - 14 July 2011](https://reader036.vdocument.in/reader036/viewer/2022062408/56649efe5503460f94c13849/html5/thumbnails/29.jpg)

1. Roll out the new communications approach (incl. major emphasis on routine immunization & other convergence messaging).
2. Sustain the SMNet in UP and Bihar, and consolidate capacity in West Bengal.
3. All states should have a media & IEC as key elements of WPV emergency response plans (incl. designated government spokesperson!)
Recs: Communications

Q7: How should the program begin to
prepare for the next phase of polio
eradication?
![Page 32: Deliberations of the 23 rd IEAG 13 - 14 July 2011](https://reader036.vdocument.in/reader036/viewer/2022062408/56649efe5503460f94c13849/html5/thumbnails/32.jpg)
IEAG Conclusion 7: Given the recent eradication progress,
and the long timelines for post-eradication
planning, this work should be intensified
esp. in the absence of high season
transmission.
![Page 33: Deliberations of the 23 rd IEAG 13 - 14 July 2011](https://reader036.vdocument.in/reader036/viewer/2022062408/56649efe5503460f94c13849/html5/thumbnails/33.jpg)
1. intensify implementation of the Global Action Plan for Poliovirus Containment (targeting completion of phase 1 by end-2012)
2. accelerate research & product development agenda (e.g. mucosal immunity, mathematical modeling, safe & affordable IPV approaches)
3. consider convening special IEAG-NTAGI session in late 2011
Recs: Post-eradication planning
![Page 34: Deliberations of the 23 rd IEAG 13 - 14 July 2011](https://reader036.vdocument.in/reader036/viewer/2022062408/56649efe5503460f94c13849/html5/thumbnails/34.jpg)
Conclusion
![Page 35: Deliberations of the 23 rd IEAG 13 - 14 July 2011](https://reader036.vdocument.in/reader036/viewer/2022062408/56649efe5503460f94c13849/html5/thumbnails/35.jpg)
India is definitely on the right
path to finish eradication.
HOWEVER, a more aggressive
approach is essential to manage the
risks along this path!
