Programme Priorities
Risks
• Importation of Wild Poliovirus
from endemic countries, esp.
considering political situation in
Afghanistan
• Emergence of VDPVs
• Missed transmission due to
inadequate surveillance
sensitivity
Priorities
• High coverage during Polio
SIAs, with focus on
vulnerable children in HRAs
• High routine immunization
coverage with bOPV and IPV
(including fIPV-3)
• Highly sensitive AFP
Surveillance
3rd March 2024 (29 States)
To be decided (7 States)
Map of States going for NID March 2024

Summary
•India maintains polio free status since 2011
•High risk of Poliovirus importation in the country
- Wild Polio virus transmission ongoing in Afghanistan and Pakistan
- Intense cVPDV2 transmission
•Sensitivity of AFP surveillance had declined in 2020, 21 due
to COVID-19 pandemic but is on recovery since 2022.
- Orient staff to report all cases of AFP
- Intensify active case searches
•Conducting quality SNID is important
