Background

Johns Hopkins University is a private research university in Baltimore, Maryland, whose Bloomberg School of Public Health runs disease-tracking projects widely cited by public-health bodies and journalists.

Its measles tracker was cited by the Center for Infectious Disease Research and Policy (CIDRAP) at the University of Minnesota as the source for calling 2026 the United States' worst measles year since 1991, after confirmed cases passed 2,318 by 24 July, overtaking the 2,289 recorded across all of 2025. The university's broader reputation for infectious-disease modelling, built during earlier outbreaks including COVID-19, is part of why its trackers are treated as an authoritative reference point rather than one dataset among many.

Common Questions
What is Johns Hopkins University's measles tracker?
Johns Hopkins University maintains a US measles case tracker cited by CIDRAP as the basis for calling 2026 the worst US measles year since 1991, after confirmed cases passed 2,318 by 24 July, overtaking the 2,289 recorded across all of 2025.Source: event
Why is 2026 called the worst US measles year since 1991?
CIDRAP, citing the Johns Hopkins tracker, calls 2026 the worst US measles year since 1991 because confirmed cases (2,318 by 24 July) have already exceeded the 2,289 recorded in all of 2025, and 1991's full-year total was 2,126, fewer than 2026 had logged by late July.Source: event

How does Johns Hopkins track disease outbreaks beyond measles?
Johns Hopkins built one of the most widely cited COVID-19 case dashboards through its Coronavirus Resource Center, and that same case-tracking approach underpins the university's current US measles tracker, the one CIDRAP cited in its 2026 record-year reporting.Source: Johns Hopkins Coronavirus Resource Center
