Your summary aligns with recent data on wild poliovirus type 1 (WPV1) cases, and the risk to India is indeed a concern due to its proximity to Pakistan and Afghanistan, the only two countries where WPV1 remains endemic. Below is an updated overview based on the latest available information, including the context you provided and additional details from recent sources:

Global Wild Poliovirus (WPV1) Cases Overview

• 2025 (as of May 31, 2025):
• Total global WPV1 cases: 12
• Pakistan: 10 cases, with recent reports confirming cases in Sindh and Punjab provinces. The upward trend in cases since mid-2023, particularly in Khyber Pakhtunkhwa, Sindh, and Balochistan, is concerning. Environmental surveillance also detected 80 WPV1-positive samples (71 from Pakistan, 9 from Afghanistan).
• Afghanistan: 2 cases, with the first case reported in Badghis province in 2025. Increased environmental detections, particularly in the South Region (e.g., Kandahar), indicate ongoing transmission.
• 2024:
• Total global WPV1 cases: 99
• Pakistan: 74 cases, a significant increase from 2023, with transmission re-established in historical reservoirs like Peshawar, Karachi, and Quetta Block.
• Afghanistan: 25 cases, primarily in the South Region, with notable geographic spread to new provinces.
• 2023:
• Total global WPV1 cases: 12
• Pakistan: 6 cases, with a large increase in environmental detections (82 positive samples).
• Afghanistan: 6 cases, with transmission limited to a few districts, particularly in the east.
• 2022:
• Mozambique: 8 cases, genetically linked to a 2021 case in Malawi, marking the first WPV1 outbreak in the African region since 2016. No cases reported since August 10, 2022, and the outbreak was declared closed in May 2024.
• 2021:
• Malawi: 1 case, linked to a Pakistan strain, with no further cases reported. The outbreak was closed in May 2024.

India’s Risk

India was declared polio-free in 2014, a monumental achievement driven by extensive vaccination campaigns and robust surveillance. However, the risk of reintroduction persists as long as WPV1 exists globally, particularly in neighboring Pakistan and Afghanistan. Key factors contributing to India’s vulnerability include:

1. Geographic Proximity and Cross-Border Movement:

• India shares a porous border with Pakistan, and population movement (e.g., trade, migration, or undocumented travel) increases the risk of WPV1 importation. The large-scale return of undocumented migrants from Pakistan to Afghanistan (over 600,000 recorded by IOM and UNHCR) highlights the potential for cross-border spread, which could extend to India.
• Historical examples, such as the 2021–2022 WPV1 outbreak in Malawi and Mozambique linked to Pakistan, underscore the potential for long-distance transmission.

1. Vaccine Coverage Gaps:

• While India maintains high routine immunization coverage with inactivated polio vaccine (IPV), pockets of under-vaccinated or unvaccinated children, particularly in high-risk areas like Uttar Pradesh and Bihar, remain vulnerable. These areas have historically been polio hotspots due to high population density and poor sanitation.
• The oral polio vaccine (OPV) is no longer used in India’s routine immunization program (replaced by IPV since 2016), reducing the risk of circulating vaccine-derived poliovirus (cVDPV) but requiring sustained high coverage to prevent WPV1 outbreaks.

1. Environmental Surveillance:

• India conducts robust environmental surveillance for poliovirus in sewage systems, particularly in high-risk areas. No WPV1 has been detected since 2011, but continued vigilance is critical given the intense transmission in Pakistan and Afghanistan’s southern cross-border corridor (Quetta Block and South Region).

1. Global Context:

• The World Health Organization (WHO) and the Global Polio Eradication Initiative (GPEI) emphasize that polio remains a Public Health Emergency of International Concern (PHEIC) due to the risk of international spread.
• Posts on X highlight ongoing concerns about polio’s endemicity in Pakistan and Afghanistan, with Pakistan’s 2025 cases already at 10 and vaccination campaigns targeting 45.4 million children underway.

Mitigation Efforts

• India’s Strategy:
• India continues mass vaccination campaigns with IPV, targeting children under 5, and maintains acute flaccid paralysis (AFP) surveillance to detect potential cases early.
• Cross-border vaccination posts and collaboration with Pakistan and Afghanistan through WHO and GPEI help mitigate importation risks.
• Public awareness campaigns counter vaccine hesitancy, which remains a challenge in some communities.
• Pakistan and Afghanistan:
• Pakistan launched its third national polio campaign of 2025, aiming to vaccinate 45.4 million children under 5, though challenges like vaccine distrust, security risks, and missed children persist.
• Afghanistan faces additional hurdles due to the Taliban’s restrictions on door-to-door vaccination, leading to reliance on less effective site-to-site or mosque-to-mosque campaigns.

Recommendations for India

To maintain its polio-free status:

• Strengthen Surveillance: Continue environmental and AFP surveillance, especially in border areas and high-risk states.
• Boost Immunization Coverage: Address gaps in routine immunization and ensure IPV booster doses are accessible in underserved regions.
• Cross-Border Coordination: Enhance collaboration with Pakistan and Afghanistan for synchronized vaccination campaigns and real-time data sharing.
• Public Health Preparedness: Maintain emergency response plans for potential WPV1 importation, including rapid response vaccination drives.

Conclusion

The 12 global WPV1 cases in 2025 (10 in Pakistan, 2 in Afghanistan) and the significant case increase in 2024 (99 cases) highlight the ongoing challenge of eradicating polio. India’s polio-free status is at risk due to its proximity to endemic countries and the potential for cross-border spread. Sustained vigilance, high vaccination coverage, and regional cooperation are critical to preventing a resurgence.
