U.S. loses measles elimination status as cases top 5,400
The Pan American Health Organization announced that the United States has lost its measles elimination status after more than 5,400 cases were reported in 2026. A PAHO-appointed expert group met earlier this year to assess whether continuous transmission since January 2025 meant the U.S. no longer met elimination criteria, ABC News reported. CDC Director Dr. Erica Schwartz told Reuters, as cited by CNN, that the agency will keep its measles response unchanged even if the status is revoked.
The CDC later reported over 5,400 infections and ten deaths, ABC News and NBC News said. An independent expert panel, described by CNN, confirmed the loss of status after sustained transmission.
