Islamabad – July 9, 2024 Sewage samples from three previously infected districts have tested positive for wild poliovirus type 1 (WPV1).

The Regional Reference Laboratory for Polio Eradication at the National Institute of Health has notified that environmental samples collected between June 11 and June 13 from Karachi South, Karachi Korangi and Dera Bugti contained WPV1.

All positive samples are genetically linked to the YB3A genetic cluster of WPV1, which has been detected in all positive cases and sewage samples reported this year.

The Pakistan Polio Programme conducted a polio campaign last week in 41 districts from July 1 to July 7 during which more than 8.4 million under the age of five were vaccinated. This was the sixth polio campaign of the year.

With the virus reported in 49 districts of the country so far this year, it is essential for parents across the country to understand that this virus continues to pose a constant threat to the wellbeing of their children and make sure to open their doors to vaccinators to receive the polio vaccine.

Polio is a devastating incurable disease that can leave a child paralyzed for life. Repeated vaccination is essential to protect children from disability caused by poliovirus. The Pakistan Polio Programme urges all parents and caregivers to ensure that their children are vaccinated against polio at every opportunity and have completed all routine vaccinations to protect them from 12 vaccine-preventable childhood diseases. 


Polio is a highly infectious disease caused by poliovirus mainly affecting children under the age of five years. It invades the nervous system and can cause paralysis or even death. While there is no cure for polio, vaccination is the most effective way to protect children from this crippling disease. Each time a child under the age of five is vaccinated, their protection against the virus is increased. Repeated immunisations have protected millions of children from polio, allowing almost all countries in the world to become polio-free, except for the two endemic countries of Pakistan and Afghanistan.
