Pakistan Confirms 45th Poliovirus Case in 2024

The Global Polio Eradication Initiative (GPEI) confirmed that seven countries reported new polio cases involving wild poliovirus type 1 (WPV1) last week.

As of November 6, 2024, Pakistan reported 45 WPV1 cases this year. With 53 WPV1-positive environmental samples collected in September and October, Pakistan's outbreak may continue for months.

Five countries in Africa reported more vaccine-derived poliovirus cases, including Senegal, which had its first circulating vaccine-derived poliovirus type 2 (cVDPV2) case for the year. The other four are the Democratic Republic of the Congo, Ethiopia, Niger, and Nigeria.

In the Middle East, Yemen reported two cVDPV2 cases with paralysis onset in September.

The U.S. CDC's travel health advisory continues to identify 37 countries at risk for poliovirus outbreaks.

The CDC says that adults who previously completed the full, routine polio vaccine series may receive a single, lifetime booster dose of polio vaccine before traveling to any destination listed. Pre-departure polio vaccination services are offered at travel clinics and pharmacies in the U.S.
