# ‘World’s most contagious disease’ on track for highest US cases in 35 years

> **Open Intelligence Dossier** · First detected: 2026-07-01 19:07 UTC · Category: Health

## Executive Summary
Measles cases in the United States have surpassed 2,000 in 2026, threatening the nation's measles-free status as infections reach a 35-year high.

## Intelligence Brief
The United States is experiencing its largest measles outbreak in decades, with total confirmed cases for the year exceeding 2,100. While a localized outbreak centered in Spartanburg has shown signs of slowing and a separate 997-case incident in South Carolina has concluded, the overall national trajectory remains significant.


Coverage from outlets including Drug Topics, Medical Daily, and AOL notes that the rising case numbers put the country at risk of losing its official measles-free status by November 2026. Reports detail how the disease has spread within vaccine-hesitant communities, leading some experts to suggest that the status of elimination has already been compromised in substance.


Future developments hinge on whether current transmission rates continue to climb toward a 35-year record. Meanwhile, a New Haven biotech company is currently developing a new treatment for the disease, and professional medical guidance is being issued to specialists such as gastroenterologists and hepatologists.
