Five Countries Confirm Polio Cases
The Global Polio Eradication Initiative's (GPEI) reported on December 23, 2020, five countries confirmed new wild poliovirus type 1 (WPV1) and circulating vaccine-derived poliovirus type 2 (cVDPV2) cases last week.
These countries include Afghanistan: two WPV1 and 23 cVDPV2 positive environmental samples; Pakistan: one WPV1 and 11 cVDPV2 cases; Benin: one cVDPV2 positive environmental sample; Burkina Faso: six cVDPV2 cases; Chad: two cVDPV2 cases; and South Sudan: 10 cVDPV2 cases and one cVDPV2 positive environmental sample.
Additionally, the GPEI has published a global cVDPV resource document aimed at providing a high-level overview of cVDPVs, their importance to the program, and their strategy for responding to them, including nOPV2.
In the USA, the CDC recommends that before traveling to the identified countries, adults who completed their routine polio vaccine series as children should receive a single, lifetime adult booster dose of polio vaccine. Since 2000, the inactivated polio vaccine is the only polio vaccine that has been given in the USA, while the oral polio vaccine is offered in other countries.
