Polio Threat Persists: 40 Samples Test Positive Across Pakistan
A recent surge in polio cases has sparked concern in Pakistan, with a startling number of environmental samples testing positive for the poliovirus. In December 2025, a total of 40 samples from various regions revealed the presence of this debilitating virus, leaving health authorities on high alert.
The National Institute of Health's polio laboratory in Islamabad conducted an extensive analysis of 127 sewage samples collected from 87 districts across the four provinces and the federal capital. The results were both reassuring and alarming. While 87 samples indicated no trace of the virus, 40 samples tested positive, raising questions about the effectiveness of vaccination efforts.
Pakistan's diverse regions exhibited varying levels of virus presence. Balochistan, with 23 samples tested, had 2 positive results; Khyber Pakhtunkhwa showed 8 positives out of 34 samples; Punjab had 6 positives from 31 samples; and Sindh's 23 positive samples out of 29 tested were particularly concerning. Even the federal capital, Islamabad, had one positive sample out of five. However, Azad Jammu and Kashmir and Gilgit-Baltistan showed no presence of the virus in their five tested samples.
But here's where it gets controversial: the official explained that a positive sample doesn't necessarily mean an outbreak. It simply indicates the presence of the virus in the environment. A positive case, on the other hand, refers to a child paralyzed by the virus. This distinction is crucial for understanding the situation's severity.
The official clarified, "When the virus is found in sewage, it means the vaccination campaign in that area needs reinforcement. We immediately launch polio campaigns to eradicate the virus upon detecting its presence." The frequent movement of people between cities can lead to polio cases anywhere, but the virus in sewage water is a red flag for inadequate vaccination coverage and declining immunity among local children.
In 2025, Pakistan's National Emergency Operations Centre for Polio Eradication led an ambitious effort, conducting six vaccination campaigns, five nationwide and one subnational, reaching an impressive 45 million children. Despite these efforts, the recent positive samples suggest that more work is needed.
The government's roadmap for 2026 starts with a nationwide polio campaign from February 2-8, targeting the four provinces, Azad Jammu and Kashmir, Gilgit-Baltistan, and Islamabad, aiming to vaccinate over 45 million children under five. Additionally, free routine immunization services are provided for children up to two years old, ensuring comprehensive protection against polio and other preventable diseases.
The authorities emphasize the importance of parents and caregivers ensuring that children under five receive polio drops during every vaccination campaign, protecting them from a lifetime of disability. This collective effort is crucial in the battle against polio.
As Pakistan continues its fight against polio, the recent findings serve as a stark reminder that the virus remains a persistent threat. The success of vaccination campaigns relies on widespread participation and consistent efforts to reach every child. With dedicated action, Pakistan can turn the tide against polio and safeguard its children's future.
