[The Pan American Health Organization no longer identifies the United States as a measles-free country] On November 14, the Wall Street Journal and CNN quoted people familiar with the matter as reporting that the Pan American Health Organization has decided to no longer identify the United States as a measles-free country. The Pan American Health Organization is the regional agency of the World Health Organization. For a country or region to be considered measles-free by WHO, it must have no locally transmitted cases of the same strain for more than 12 consecutive months. The United States was declared measles-free in 2000, but the number of measles cases in the United States since 2025 has exceeded the total number of cases in the 25 years from 2000 to 2024.
