Abstract

|
The Global Polio Eradication Initiative (GPEI) has made great progress in eradicating wild poliovirus (WPV) such that polio cases due to WPV decreased by over 99%, from an estimated 350,000 cases in 1988 to 2,849 cases in 2000. Despite global efforts, a total of 176 WPV cases and 367 circulating vaccine-derived poliovirus (cVDPV) were reported in 2019, indicating an upsurge from the number of cases in 2018. In Korea, the last polio case was reported in 1983, and the country became certified as polio-eradicated in 2000. Since 2004, the inactivated poliovirus vaccine (IPV) has been used exclusively, and the immunization rate has remained high. Nevertheless, the risk of polio importation by international spread still exists. To remain a polio-free country, it is important to maintain a high vaccination rate and to be prepared for poliovirus importation by establishing a national guidance for polio vaccination for travel to and from countries affected by poliovirus, and a national response to a poliovirus event or outbreak.
