1. Sewage Testing & Early Warning
To stop polio, the programme doesn't just wait for children to show symptoms. Wastewater samples are systematically collected from designated open sewage channels in major cities and analyzed at our state-of-the-art laboratories.
If poliovirus genetic material is found in a sample, it serves as an early warning that the virus is silently circulating in the community. This allows local health departments to deploy vaccinators immediately, creating a wall of immunity before clinical paralysis cases can emerge.
2. World-Class WHO Laboratories
Pakistan has established two high-level polio reference laboratories certified directly by the World Health Organization. These facilities conduct molecular sequencing to determine the exact strain active in each area (Wild Polio Type 1, cVDPV1, cVDPV2).
3. The 18 Core Reservoir Cities
Surveillance data has pinpointed 18 high-risk cities where transmission is most resilient. These areas receive priority resource allocation during vaccination campaigns.
Sindh
Punjab
Khyber Pakhtunkhwa (KP)
Balochistan
Gilgit-Baltistan
Azad Jammu & Kashmir (AJK)

Environmental monitoring shows that the virus can travel quickly through major transit corridors. Always ensure your children are vaccinated during every door-to-door campaign.
