Poliovirus detected in 22 samples despite nationwide vaccination drive

ISLAMABAD: National Emergency Operation Center (NEOC) has confirmed the presence of poliovirus in 22 environmental samples collected from different parts of the country, despite recent progress in vaccination efforts, here on Monday.

As per the NEOC, 56 environmental samples were collected from 44 districts, of which 22 tested positive for the virus. Officials acknowledged that the presence of the virus remains a challenge but credited recent immunization campaigns with significantly reducing transmission.

The second national polio campaign of 2025 was conducted from April 21 to 27, vaccinating more than 45.3 million children under the age of five. Health authorities reported strong coverage across the country, noting that all provinces and territories met or exceeded their targets.

The NEOC said “back-to-back immunization campaigns in February and April” were key to the recent decline in virus circulation. However, it stressed that “continuing vigilance is essential to prevent further spread.”

The third nationwide campaign is set to begin next month. The NEOC urged parents to fully cooperate with health workers and ensure that all eligible children are vaccinated. It also reiterated that repeated doses of the oral polio vaccine “are essential to develop safe and long-lasting immunity.”
