Other polio news:

At 7:00-8:30 a.m. (Central) on Monday, March 9th, the Global Polio Eradication Initiative will celebrate International Women’s Day with a webinar on “Women Pioneers in Polio Eradication”. Participants will learn about the roles women play to support eradication efforts, hear about the impactful work happening on the ground, and identify best practices for engaging women. Register here and join the Zoom link here at the time of the webinar.

The war surrounding the Persian Gulf has not yet directly impacted polio eradication operations in Pakistan and Afghanistan. Cross-border cooperation between Pakistan and Afghanistan polio eradication programmes continues through established mechanisms, recognizing that poliovirus does not respect borders. Recent border closures have affected the shipment of environmental and stool samples from Afghanistan to the Regional Reference Laboratory in Islamabad. Alternative air shipments are currently in use.
