Regional Verification of Measles Elimination
By the end of 2021, 76 (39%) countries had been verified by independent regional commissions as having achieved or maintained measles elimination status. No WHO region had achieved and sustained elimination, and no African Region country has yet been verified to have eliminated measles. WHO's Region of the Americas achieved verification of measles elimination in 2016; however, endemic measles transmission was reestablished in Venezuela (2016) and Brazil (2018). Since 2016, endemic transmission has been reestablished in eight other countries (Albania, Cambodia, Lithuania, Mongolia, Slovakia, the Czech Republic, the United Kingdom, and Uzbekistan) that had previously achieved verification of measles elimination.
