Tracking Progress Toward Polio Eradication — Worldwide, 2013–2014
CDC Media Relations
Improvement in the quality of surveillance for polioviruses is needed to help strengthen global polio eradication efforts. There are only three countries where poliovirus circulation has never been interrupted: Afghanistan, Nigeria, and Pakistan. Outbreaks occurred during 2013 and 2014 as a result of spread from these countries. Monitoring the progress of the Global Polio Eradication Initiative requires sensitive and timely polio surveillance. This report presents 2013 and 2014 poliovirus surveillance data, focusing on reports during 2010-2014 from 29 countries with at least one case of wild or circulating vaccine-derived poliovirus. In 2013, 25 of the 29 countries met the two primary surveillance quality indicators: sensitivity and timeliness; in 2014, the number decreased to 21. To complete and certify polio eradication, gaps in surveillance must be identified and surveillance activities, including supervision, monitoring, and proper specimen collection, must be further strengthened.
