Montana

Montana is experiencing active measles transmission, a highly contagious viral illness with potential for severe complications, reflected in a medium public health impact designation. As of 2026-08-21, there are 2,566 confirmed measles cases, and the trend is increasing; no deaths are reported in the available data. The quantified burden indicates sustained and expanding transmission rather than a contained cluster. No other pathogens are documented as active in the provided reports, so there is no evidence here of multi-pathogen co-circulation.
