Counts are confirmed cases by the jurisdiction that reported them, as CDC lists them. CDC counts some cases that are not reported by any of these jurisdictions, so the table can add up to less than the national total.

The key facts at the top give CDC's national count of confirmed measles cases this year, with last year's total and the share of cases hospitalized. The table lists the count for each state and jurisdiction CDC reports, highest first.

## What the count includes

CDC says its counts include only confirmed cases that jurisdictions have notified to CDC, and that it is aware of probable cases that are not in these numbers. The table lists jurisdictions as CDC does, so New York City appears separately from New York. CDC says its counts for 2025 and 2026 are preliminary and subject to change.

## Why a state's own count can differ

CDC says state health departments and CDC post measles counts on different schedules, so a state's website can show a different number, and that states have the most up-to-date information about cases and outbreaks in their jurisdictions.

## When it updates

CDC updates these counts once a week, with data as of noon on Thursday. This page reads CDC's data every few hours and updates at the same address after each CDC update.
