The Guardian report on the measles outbreak said the United States could lose its measles elimination status this week, an outcome the paper said would likely cement the legacy of health secretary Robert F. Kennedy Jr. in vaccine policy. The article, written by Jessica Glenza and published on November 11, 2026, links the possible change to what the outlet described as an anti-vaccine agenda pushed by Kennedy.
According to The Guardian, the country is in the middle of its worst measles outbreak since 1991, with more than 5,400 cases nationally. The paper described the outbreak as the "worst outbreak of the virus in the US in 35 years."
The Guardian said that if the United States loses its measles-free status, it would join Canada. The outlet's account centers on the timing of a decision it said could come this week, with the scale of the outbreak as the backdrop for that decision.
No other outlet's reporting on the matter was available for this story, so the account rests on The Guardian's report alone. The paper's headline and summary both tie the expected development to Kennedy's record on vaccines, and the report is the only source for the figures and timing described here.
