As of late February 2026, the United States is facing a public health crisis that threatens to overturn a 25-year milestone. According to the latest CDC data released on February 20, the U.S. has recorded 982 confirmed measles cases in just the first seven weeks of the year.
This surge comes on the heels of a record-breaking 2025, which saw 2,281 cases—the highest annual total since 1992. Health officials warn that the U.S. is now on the verge of losing its “measles elimination” status, a designation held since the year 2000.
The 2026 Outbreak: Key Statistics
The current wave is characterized by rapid transmission within localized “immunity gaps”—communities where vaccination rates have fallen below the 95% herd immunity threshold.
| Category | 2026 Data (as of Feb 19) | Trend Comparison |
| Total Confirmed Cases | 982 | 4x the typical annual average. |
| Active Jurisdictions | 26 States + NYC | Broadest geographic spread in decades. |
| Vaccination Status | 94% Unvaccinated | Primarily among those with “unknown” or “declined” status. |
| Age Demographic | 59% (Ages 5–19) | Heavily concentrated in school-aged children. |
| Hospitalization Rate | 4% (38 cases) | Risk remains highest for children under 5. |
State-Level Hotspots
While the virus is present in 26 jurisdictions, a few states are experiencing disproportionately large outbreaks that are straining local public health resources.
South Carolina: Currently home to the largest outbreak in modern U.S. history, with 962 cases reported by the state’s Department of Public Health on February 20. The epicenter is Spartanburg County, where the virus has spread through private schools with low vaccination coverage.
Washington State: Snohomish and Clark counties are battling active outbreaks, with 26 confirmed cases as of February 21.
California: Reporting 19 cases across multiple counties, including localized outbreaks in Shasta and Orange counties.
Illinois: Recorded its first case of 2026 in the Metro East area on February 13, linked to an individual who recently traveled out of state.
The “Elimination Clock” is Ticking
Under the Pan American Health Organization (PAHO) framework, a country loses its “eliminated” status if a single chain of transmission of the same virus lineage continues uninterrupted for 12 months.
The April Deadline: PAHO has invited the U.S. and Mexico to a high-level review on April 13, 2026. If researchers determine that current outbreaks are linked to the 2025 chains (such as the major Texas outbreak that began in January 2025), the U.S. will officially lose its elimination status.
