Current Outbreak Overview
The United States is experiencing a significant resurgence of measles, with approximately 1,575 cases reported in 2026, surpassing the previous year's totals, which marked the highest annual cases in over 30 years. The Centers for Disease Control and Prevention (CDC) has identified 16 new outbreaks across more than 30 jurisdictions, including states such as California, Florida, and New York. Notably, South Carolina accounts for over 600 of these cases, while Utah's ongoing outbreak has reported 318 infections.
Contributing Factors
The rise in measles cases is largely attributed to declining vaccination rates and increased exemptions from vaccination requirements. The vaccination coverage for the measles, mumps, and rubella (MMR) vaccine in children has decreased from 95.2% during the 2019-2020 school year to 92.5% in the 2024-2025 school year. The CDC indicates that about 92% of this year's measles cases involve individuals who are unvaccinated or whose vaccination status is unknown. A report from the Common Health Coalition warns that even a 1% drop in MMR vaccination rates could lead to an additional 17,000 measles cases annually.
Localized Outbreaks: Case Study of Washtenaw County
In Washtenaw County, Michigan, a measles outbreak has expanded to seven confirmed cases, all involving unvaccinated individuals. The first known case was traced back to an unvaccinated adult who traveled to Florida. Health officials emphasize the rapid transmissibility of measles, urging those exposed to seek vaccination within 72 hours to mitigate further spread. Dr. Juan Luis Marquez, the county's medical director, highlighted the urgency of vaccination, stating, “Measles spreads rapidly when people are unprotected by vaccination or prior illness.”
Health Implications and Recommendations
Measles is highly contagious, with the CDC noting that up to 90% of unvaccinated individuals in close proximity to an infected person may contract the virus. Symptoms typically manifest within 7 to 14 days post-exposure and can lead to severe complications, including pneumonia and encephalitis. The CDC reports that 1 in 5 individuals infected with measles will require hospitalization, and the mortality rate for measles can be as high as 1 in 1,000 among children.
Health authorities are urging residents to check their vaccination records and ensure they are up to date with the MMR vaccine, which offers 97% protection after two doses. In Michigan, only 66% of children aged 4-6 have received the recommended two doses, a decline from 89% in previous years.
Official Statements & Responses
Dr. Natasha Bagdasarian, Michigan's chief medical executive, remarked on the alarming spread of measles, stating, “Measles cases are spreading like wildfire this year.” The CDC is set to review the U.S. measles elimination status in November, raising concerns that the country may lose its designation of measles elimination, which has been in place since 2000.

Conflicting Reports & Gaps
While the CDC reported 1,487 confirmed cases in 32 states as of March 20, the current total of 1,575 cases indicates a rapid increase, highlighting the need for ongoing monitoring and public health interventions. The exact number of cases and outbreaks may vary as new information becomes available.
