  • Inherent Challenges in Bihar High Risk Blocks with unique social, demographic and geographic features Population density/ Birth rate, Water/ sanitation issues, Access Compromised Areas and Socio-economic disparities.

    Annual flooding in Kosi riverine areas

    High migration from the state

    Gaps in Routine Immunization coverage

  • The risks to Polio situation in BiharRe-introduction of transmission through importation:High migration from/ to the stateFrequent intermixing of population with Nepal Foci of transmission outside UP/ Bihar in 2010 genetically linked to 2009 transmission of BiharWho took it there.can bring it back!!

    Re-establishment:Decreased population immunityComplacencyLow RILess opportunity with SIAs

    High transmission season compounded by possibility of floods in high risk areas

    Probability of very low level undetected transmission

  • What is being done?Sustaining high population immunity specially in High Risk Areas by:High quality SIAs in frequency & scope as per the GOI guidelines.

    Steps to strengthen Routine Immunization.

    Implementation of Kosi Operational Plan.

    Implementation of 107 Block Plan.

    Strong oversight from state level.

    Intensified surveillance in core endemic areas of Kosi and environmental surveillance.

  • What is being done?Preventing risk of re-importation through Coverage of :Migrants in Bihar (Nomads, Brick Kiln labours etc.)

    Incoming migrants during period of major movement.

    Major congregations.

    Continuous Vaccination at major entry points & Indo-Nepal border.

    Prepared for mounting Rapid Mop Up in response to any transmission detected.

  • High quality of SIAsHigh quality SIAs: >99% evaluated coverage consistently.High focus in High Risk areas.

  • Concerns from BiharOnly 2 SIAs in 2nd half of 2011 which is high transmission period in Bihar.

    Incidences of Mass refusals/ Cluster of refusal at Patna Urban.

    Erratic SIA and RI vaccine supply

    Operational feasibility: Rs 650 per vehicle/ day (incl POL) for vaccine mobilizationSame since 2002.

    Sustaining motivation of vaccinators:Only Rs 75 per day for vaccinators

  • High transmission period & SIA opportunityConcerns from Bihar1

  • Mass refusals:Due to development related issues:Demands of Road/ TubewellICDS ServicesSchool etc

    Some remain unsolved and occur repeatedly!Incidences of Mass refusalsCommunity related refusals:Responsible for only 0.1% of remaining X houses of state

    1631 refusal houses remaining at the end of June round in whole state

    But, 56% of this (910) in just 3 planning units of Patna Urban (having 0.8% houses of state)

    Persisting over the time.Concerns from Bihar2

  • SummaryThere has been immense progress with no P1 for more than 10 months & no P3 for more than 17 months.

    But, risk of importation is high considering high migration from state

    Bihar is taking all the measure to prevent importation by covering in coming population in state.

    We are maintaining sensitive surveillance to detect the transmission at the earliest.

    Bihar is prepared to respond rapidly for any importation which occurs.

  • Thank you!

    **I will be talking on progress made and remaining challenges in Polio Eradication in Bihar.*There is very strong political commitment in Bihar. Recently Hon CM briefed all MLAs and ministers in Bihar assembly on Polio. I will like to show you a small clip from the same.*Bihar has made significant progress. As you can see the number of Polio cases have gone down from 503 in 2007 to just 9 in 2010 and no cases till now in 2011. As you will note, historically most of the cases have been coming from North Central part of Bihar. *When we look at core endemic areas of Bihar, this area has been Polio free since last 17 months which is longest ever polio free period for this area. The bOPV was introduced in Jan2010 and might have acted as tipping factor.*Bihar has no indigenous WPV1 since Nov09 and no WPV3 since Jan10. There was importation of WPV1 in mid 2010 from Nepal which was curbed with two quick mop up rounds. The traditional reservoir are of Kosi has been P1 free for more than 20 months which longest ever polio free period.

    *These are the recommendations from the last IEAG Meeting in Nov10 for action at our level. As you can see, we have implemented most of recommendations and some are still in process.*Bihar has inherent challenges to Polio eradication such as High Risk Blocks with unique features, Annual flooding in kosi riverine area, high migration in/ out of Bihar and gaps in routine immunization coverage.**Although we look to be in good position but some major risks are still there. Of which the risk of importation is very high as the state has high migration and most of the cases of 2010 outside UP/Bihar had genetic linkage with the 2009 transmission of Bihar.

    Secondly there is risk of decreasing population immunity which will help the transmission to get established if it comes back. This low population immunity can be caused by lesser opportunity with SIAs, Complacency and low existing RI coverage.

    These risks are very high in coming few months as this is high transmission season and is further compounded by possibility of floods.

    Lastly, although very remote, but there is possibility of very low level undetected transmission. **To mitigate the risks as described, we have taken steps to sustain high population immunity by conducting frequent high quality SIAs, improving RI, Implementing Kosi Operation Plan and 107 Block Plan.

    To detect even low level of transmission, we have intensified surveillance in core endemic areas of Kosi and have also started environmental surveillance. **To prevent the importation, we are covering migrant families, incoming migrants during festival seasons and also major congregations. Seeing the risk of importation, we have put the continuous vaccination booths at major entry points and Indo-Nepal border.

    Despite these, if importation occurs, we are fully prepared to mount high quality Mop Up response within 10 days of detection of transmission. **Bihar has maintained very high quality of SIAs with more than 99% coverage in every campaign. The end of round coverage surveys show that we miss less than 1% children.

    The quality is much higher in high risk blocks and Kosi riverine areas.*Kosi Riverine area has acted as reservoir of transmission over the years and is highly crucial area for achieving the goal of eradication. This area is free from P1 for around 20 months now.

    *The area in question is highly challenging in terms of access and gets flooded every year for 3-5 months.**This has been achieved through implementation of Kosi Operational plan. With this plan the reach to Kosi area was increased by establishing Satellite offices and stay points, human resources were intensified. In this area, frequent basa validation is being done and all teams are being monitored in every round.

    This has resulted in improved coverage as seen in less than 0.5% children being missed in SIAs and even the children missed in Basas reduced to 2% from 14% in 2009.******This year we had importation of transmission from Nepal. Although there was internal circulation giving rise to 3 cases, but transmission was limited to a small geographical area bordering to Nepal.

    2 Quick mop up rounds were done in the area covering 1.8 million children in each round. Through our sensitive surveillance system, we picked the transmission early and mounted the response within 10 days of getting stool results.

    With the last case having onset on 1st September, it looks like that the transmission has stopped.

    This shows that we are vulnerable in areas where there is large intermixing of population like at the Nepal border or during festival seasons when migrant families return to Bihar. And also that, if we have high background population immunity, we can stop the transmission by doing quick mop rounds in sufficiently large areas.****We have revised incentive scheme for improving the fund flow. All DIOs have been trained on Routine Immunization and the training of all Medical Officers is going on.

    Monitoring has been intensified with around 5000 session and 30,000 houses being monitored every month. We have developed process indicators to review the performance of RI in the districts on monthly basis. Weekly District Control Room on RI has been formed at each district to address the gaps found during monitoring.

    We have rolled out RI in urban areas focusing on slums. Migratory Populations are being included in RI microplan for coverage. **
