MedBodh India & Public Health | Published 29 October 2026 | WHO SEARO update 28 October 2026
WHO’s South-East Asia Regional Office marked World Polio Day 2026 with a reminder that maintaining polio-free status requires continuous immunization and surveillance. The region has been certified polio-free since 2014. This does not mean that vaccination, acute flaccid paralysis (AFP) detection or importation-risk planning can stop.
What happened this week?
The WHO regional office described a webinar convened on 26 October 2026 with representatives of national programmes and technical partners. Its 28 October update highlighted three priorities: (1) regular national and subnational risk assessment; (2) preparedness and response planning; and (3) translating surveillance evidence into targeted action. WHO cited India’s experience in integrated polio and measles outbreak simulation exercises conducted in four batches between December 2025 and August 2026.
Four lessons for public-health teams
| Priority | Operational question |
|---|---|
| Routine immunization | Where are children missing recommended polio vaccine doses? |
| AFP surveillance | Are possible AFP cases detected, promptly notified, investigated and sampled according to programme protocols? |
| Laboratory readiness | Can specimens and reports reach the surveillance laboratory network through prescribed channels? |
| Outbreak planning | Are district referral, communication, response and simulation procedures current? |
WHO called for sustained routine immunization coverage and at least two doses of inactivated polio vaccine (IPV) in its regional public-health priorities. This is a regional policy message, not a replacement for a child’s age-specific Government of India National Immunization Schedule. Clinicians should follow the applicable national and state schedule when counselling families.
Practical PHC/CHC checklist
- Find missed children: Review line lists and outreach data, especially mobile, remote and underserved populations.
- AFP red flags: Promptly assess and report acute onset weakness or paralysis in children through established disease-surveillance channels.
- Coordinate specimens: Follow standard AFP stool-sampling, cold-chain and laboratory referral requirements; use trained surveillance personnel.
- Improve documentation: Avoid counting an unverified dose as administered, and reconcile session records where appropriate.
- Explain continued vaccination: A polio-free certification is a result of sustained programme work—not evidence that there is no ongoing risk anywhere in the world.
Common misconception: ‘Polio-free’ means ‘zero risk’
The certification reflects interruption of indigenous wild-poliovirus transmission under defined surveillance standards. Poliovirus may circulate elsewhere, and importation or vaccine-derived poliovirus events must be monitored and responded to. Public messages should avoid either complacency or unsupported suggestions of a new local outbreak.
