Measles and rubella elimination in the Eastern Mediterranean Region: successes and challenges.

In 2019, upon reviewing countries' reports, the regional verification commission for measles and rubella elimination declared elimination of measles and rubella in Bahrain, Islamic Republic of Iran and Oman. This achievement in the Eastern Mediterranean Region (EMR) constitutes a major success, since it occurs at a time when there remain highly challenging situations in several countries of the Region. In addition, there are unprecedented high transmission rates of measles throughout the world, with other World Health Organization (WHO) regions either not progressing (status quo) or regressing. Indeed, the WHO Region of the Americas and several other countries have in fact lost the status of measles elimination.
