Polio virus detected in 46 environmental samples across Pakistan: a call for intensified efforts
ISLAMABAD: The polio virus has been detected in 46 environmental samples collected from various cities across Pakistan, signaling an ongoing threat despite recent progress in reducing polio cases. According to officials from the Emergency Operations Center (EOC), all of the contaminated samples were collected during November 2025.
This brings the total number of positive environmental samples for 2025 to 611, with the virus detected in multiple districts across Sindh, Khyber Pakhtunkhwa, Punjab, and Balochistan. Major cities including Karachi, Hyderabad, Sukkur, Lahore, Peshawar, Bannu, and Quetta were among those affected by the contamination.
Health authorities are intensifying anti-polio campaigns and vaccination drives nationwide, but these detections underscore the stubborn persistence of the virus in certain regions.
Progress in polio cases: A deceptive decline?
According to the National Emergency Operations Center (NEOC), polio cases have dropped dramatically from 74 in 2024 to 30 in 2025. While this decline is significant, it does not present the full picture. Pakistan, like the rest of the world, should have eliminated polio by now, but this progress is far from enough, especially considering the persistent environmental detections. On the other hand, the Government of Pakistan attributes Afghanistan as a major impediment to its efforts to completely eradicate the polio virus. The virus continues to thrive in the neighboring country, where a large portion of the population continues to refuse the administration of the polio vaccine to their children.
In the ongoing battle against the virus, Balochistan and Punjab have remained polio-free for many months, and no new cases have been reported nationwide since September 2025. This suggests that vaccination efforts are having some success, particularly through six nationwide vaccination campaigns that reached over 98% of children in 2025.
However, a stark reality remains: Pakistan is still struggling to eliminate polio. Missed children during vaccination campaigns have been reduced by 18% compared to previous years, but pockets of the population are still vulnerable, especially in areas where trust deficits in health services persist.
PMA concerns: Karachi’s polio fight and data gaps
The Pakistan Medical Association (PMA) recently raised serious concerns about the ongoing risks in major urban areas, particularly Karachi. Despite improvements in vaccination coverage, data gaps and trust issues have hindered the effectiveness of campaigns. PMA's concern is that without addressing these issues, polio transmission could rise again, particularly in high-density populations.
Continuing efforts for 2026: A call for stronger action
While the NEOC emphasizes strong leadership, institutional collaboration, and frontline health workers, the persistent environmental detections paint a worrying picture of how much more needs to be done. As we head into 2026, authorities must consolidate gains and implement decisive measures to ensure that no child remains unvaccinated, especially in high-risk areas.
With an ongoing national effort, Pakistan is aiming for complete polio eradication, but the recent environmental virus detections and gaps in vaccination highlight the need for renewed vigilance.
