Measles Ranking Question
Which States Have Active Measles Outbreaks Right Now?
This dataset shows recent case-report activity, not authoritative formal outbreak status. The largest recent-report signals are Pennsylvania (312), Utah (144), Wisconsin (139); confirm outbreak or exposure notices with the relevant health department.
15-second answer
- 28 states have a recent-report signal in this dataset, led by Pennsylvania (312), Utah (144), Wisconsin (139), Ohio (121), Kentucky (103).
- CDC reports cases across 47 jurisdictions, but neither that national total nor a recent state report is a substitute for a formal health-department outbreak declaration.
- Use this page to compare state case activity, then open the specific state or travel page and follow its official sources.
- For exposure, school, or trip concerns, the next useful step is almost always the state page or destination page, not another national article.
Why this matters 1
Many measles questions are really about which places have recent case reports, not just whether there are any U.S. cases this year.
Why this matters 2
Separating recent case activity from formal outbreak declarations keeps the comparison honest and useful.

FAQ
Quick questions about this answer
Is this different from states that have had any measles cases this year?
No. This page uses recent report dates to prioritize state case activity. It does not independently determine formal outbreak status.
Why compare recent state reports instead of the U.S. total only?
Because parents, schools, and travelers usually need to know which state page to check next, while formal outbreak status still comes from public-health authorities.
