The Global Polio Eradication Initiative (GPEI) reported six countries in Africa confirmed polio cases for the week ending May 26, 2021. All of these polio cases involved vaccine-derived types.

The GPEI summary is as follows:
- Pakistan: one cVDPV2 positive environmental sample

To inform international travelers of their health risks, the U.S. CDC issued a Level 2 Travel Alert on May 13, 2021, saying, 'Some international destinations are considered high risk for polio.
Before travel to any high-risk destination, CDC recommends that adults who previously completed the full, routine polio vaccine series receive a single, lifetime booster dose of polio vaccine.'
Since 2000, the inactivated polio vaccine is most often given in the USA. The CDC recommends that children in the USA get polio vaccinated to protect against poliomyelitis.
