None. A surveillance count, not an order.
What this establishes
- A year-to-date count of 5,182 confirmed cases as of 5 November 2026, published in CDC’s update of 6 November 2026.
- As reported from the same update: 562 people hospitalized (about 11%) and 43 outbreaks in 2026.
What this does not establish
- A final 2026 total; the count is preliminary and revised.
- The number of measles deaths: CDC counted four in 2026, fewer than state health departments reported.
- Any change to the immunization schedule.
Why it matters
Measles counts are the clearest available measure of how immunization coverage is actually holding. The 2026 count is the highest since 1991.
