• De CDC bevestigde 51 extra mazelengevallen, waardoor het landelijke aantal infecties in de VS op 16 mei 2026 op 1.893 staat. • De instantie meldde dat alle behalve negen gevallen lokaal zijn opgelopen, dat er dit jaar 27 uitbraken zijn gemeld en dat 92% van de patiënten niet was gevaccineerd of een onbekende vaccinatiestatus had. • De uitbraak is significant omdat mazelen zich snel verspreiden in gemeenschappen met een lage vaccinatiegraad, en de VS is nu op weg om het aantal van 2.288 gevallen van vorig jaar te overschrijden als de transmissie aanhoudt.

• A measles outbreak in Washtenaw County, southeast Michigan, now includes 7 cases under investigation involving unvaccinated children and adults, with potential exposure at Trinity Health Ann Arbor Hospital's ER on March 21. • The latest case concerns a young child treated in Ypsilanti, raising concerns that ER visitors may have been exposed to the highly contagious virus. • All confirmed and suspected cases are among unvaccinated individuals, highlighting ongoing vaccination gaps amid the outbreak's growth reported on March 25.

• As of March 6, 2026, the United States has confirmed 1,300 measles infections this year across 30 states, putting the country on track to surpass 2025's record 35-year high numbers. • Measles has continuously circulated in the U.S. for over a year following an outbreak in Texas (January-August 2025), with ongoing outbreaks on the Utah-Arizona border and in South Carolina that drastically increased in January 2026. • The Pan American Health Organization postponed its decision from April to November 2026 on whether the U.S. should lose its measles elimination status achieved in 2000, but current trends suggest it likely will due to vaccination rates falling below the critical 95% threshold.
