Health authorities in Gilgit‑Baltistan have confirmed the presence of wild poliovirus in environmental samples collected from the Diamer District. The detection triggered an immediate public health emergency, with district and regional health teams mobilized to assess the risk, trace potential carriers, and reinforce immunization efforts.

Scope of the Threat

Poliovirus poses a significant threat to young children, particularly those under the age of five. Due to its ability to spread silently, detection in environmental samples such as sewage suggests that the virus may be circulating undetected within the community. While no clinical cases have yet been identified, health authorities are operating under the assumption that infections may already exist, necessitating rapid containment protocols.

Emergency Immunization Campaign

In response to the detection, health officials have launched a door-to-door vaccination campaign targeting all children aged 0 to 5 years across Diamer District. Mobile vaccination units are being deployed to remote villages and urban neighborhoods alike. In addition, fixed immunization points at schools and health centers are providing oral polio vaccine (OPV) doses to ensure wide coverage.

Local healthcare workers are working alongside community leaders, religious affiliates, and volunteers to build public trust and encourage participation. According to organizers, community engagement initiatives include informational leaflets, mosque announcements, and targeted household visits to spread awareness about the importance of the campaign.

Surveillance and Monitoring Efforts

Authorities are intensifying environmental surveillance, collecting sewage samples from various areas within Diamer to track the extent of transmission. This data-driven approach will guide follow-up vaccination rounds and help verify whether the virus remains active or has been contained.

Furthermore, active case finding teams comprising polio officers and health workers are visiting homes, day-care centers, and medical facilities to identify any children displaying symptoms such as acute flaccid paralysis. Any suspected cases are being promptly reported to the polio eradication network for verification and response.

Coordination Between Health Agencies

The campaign is being coordinated by the Gilgit‑Baltistan Health Department in collaboration with national entities such as the Expanded Program on Immunization (EPI), and international partners like the World Health Organization (WHO) and UNICEF. Supply chains for vaccines, syringes, and cold-chain equipment have been fortified to prevent stock-outs and ensure safe delivery of vaccines to remote and high-altitude regions.

Provincial authorities have also issued travel advisories and are monitoring inter-district and cross-border movement, aiming to prevent spillover to adjacent districts or regions with similarly vulnerable immunization coverage.

Community Engagement and Education

To counter misinformation and vaccine hesitancy, health teams have organized door-to-door counseling sessions. These include group meetings in villages and urban centers, skillfully led by trusted local figures teachers, religious leaders, and social activists who reinforce the safety of vaccines and the importance of early childhood immunization.

Risk of Re-emergence and National Implications

Pakistan has made significant progress toward eradicating polio over recent years, but the virus remains endemic in some areas. Detection in Diamer District serves as a stark reminder that gaps in immunization even in remote areas can permit the virus to re-emerge and threaten national and international eradication priorities.

What Happens Next?

Ongoing surveillance will continue for several weeks. If no further environmental or clinical cases are found, health officials will declare the district polio-free. Conversely, additional detections will trigger further immunization rounds and stricter containment measures until confirmed cleared.

Conclusion

The recent detection of poliovirus in Diamer District, Gilgit‑Baltistan, is a critical wake-up call for robust immunization coverage and continuous surveillance. Timely response, proactive vaccination, and community awareness are crucial to preventing a resurgence of polio. With coordinated government actions and community participation, authorities aim to reaffirm Pakistan’s commitment to eradicating polio once and for all.
